 +=== UEFI Secure Boot === 
 + 
 + 
 +On computers with Secure Boot enabled, extra measures may be required to boot an Operating System.  Slackware for instance, is unable to boot on a computer that has Secure Boot enabled. Historic liveslak based ISOs are also not able to boot there. From liveslak-1.5.0 and onwards, Secure Boot is supported for the 64-bit ISO images. 
 + 
 +Secure Boot enforces that the first-stage bootloader is signed with an encryption key known to Microsoft.  For Linux based Operating Systems, the most widely used solution is to place an small single-purpose bootloader before the regular Linux bootloader.  This EFI bootloader is called 'shim' Shim must be cryptographically signed by Microsoft for it to successfully boot a computer.  This is not a trivial process, Microsoft is very strict about the signing process because in essence your signed bootloader will boot anything on a Secure Boot enabled computer, including malware if that was signed by your 'distro key' That would create a huge security hole and defy the purpose of Secure Boot. 
 + 
 +Signing your Grub bootloader and your kernel also becomes mandatory, because the 'shim' refuses to load un-signed binaries.  This complicates the process of upgrading to a new kernel further. 
 + 
 +The Slackware Live OS boots on a Secure Boot enabled computer if created with liveslak-1.5.0 or newer, and only for the 64-bit liveslak ISO images.  The Slackware Linux distro does not ship a 'shim' which is signed by Microsoft, so how to get around the dilemma of requiring a signed 'shim'? 
 + 
 +To realize this, the Slackware Live ISO 'borrows' a 3rd-party 'shim'. The binaryis actually called ''bootx64.efi'' in the ''/EFI/BOOT/'' directory and has been extracted from another distro's officially signed 'shim' package; Fedora by default but the Debian and openSUSE shim are also supported by the ''make_slackware_live.sh'' script.  This 3rd-party 'shim' binary has been signed by 'Microsoft UEFI CA' which will allow it to boot on any computer. We just need to tell it that is OK to load Slackware's Grub and kernel into memory. 
 + 
 +A distro 'shim' like Fedora's contains an embedded distro SSL certificate and 'shim' will trust the signature of any binary (grub, kernel, etc) which has been signed using that certificate. Of course, 3rd-party 'shim' binaries do not embed a Slackware SSL certificate. Therefore, another means must be used to establish trust.  Secure Boot recognizes additional SSL certificates in the computer's MOK (Machine Owner Key) database as valid.  The 'shim' trusts custom SSL vertificates of signed binaries, if they are present in the MOK database.  It is up to the user (the Machine Owner) to enroll a custom SSL certificate into that database. 
 + 
 +The Grub and kernel images of Slackware Live Edition are signed with an 'Alien BOB' SSL certificate and private key.  This SSL certificate needs to be added to the MOK database of your Secure Boot enabled computer.  All liveslak ISOs use this specific certificate plus its associated private key. The private key will of course never be distributed but a 'DER-encoded' version of the public certificate is distributed as part of the ISO.  You can find it as ''/EFI/BOOT/liveslak.der'' inside the ISO. On a persistent USB stick which you created from the ISO, this will be on the second partition (the ESP). 
 + 
 +== Add the ''liveslak.der'' certificate to the MOK database == 
 + 
 +There are two ways to add or enroll this certificate. 
 +  * When you boot a Secure Boot enabled liveslak ISO for the first time, the 'shim' will fail to validate the certificate of liveslak's Grub. It will then start the 'MokManager' showing you a nice blue screen with a dialog requesting you to enroll a public key (aka the SSL certificate) from disk. You can use the file selector to browse to the 'efi' partition and there to the ''./EFI/BOOT/'' directory. Select the ''liveslak.der'' and confirm that this is the correct certificate. The computer will then reboot and after reboot, you will automatically end up in the Grub boot menu without any further intervention. 
 +  * If you already have a Linux OS up and running on that computer, you can use the program ''mokutil'' to enroll the key before you boot a liveslak ISO:<code> 
 +# mokutil --import liveslak.der</code> This command will schedule a request to shim, and the first time you boot a liveslak ISO the MokManager will ask confirmation to enroll the scheduled key.  In other words, you won't have to 'enroll from disk'
 + 
 +Note that MOK key enrollment is a one-time action for the official liveslak based ISOs.  All future liveslak ISOs will also be signed using this ''liveslak.der'' certificate and as long as it stays in your computer's MOK database, the 'shim' will load Grub and the kernel without complaint. 
 + 
 +Note that you can create your own SSL certificate plus private key and use those to generate custom liveslak ISO images with Secure Boot support.  All you need to do is to enroll the public key (the DER-encoded version of your SSL certificate) into the MOK database of your computer.  The MOK database has room for multiple keys so yours as well as liveslak's keys (and more) will fit there. 
 + 
 + 
 +=== Boot from an ISO file on disk === 
 + 
 + 
 +If you downloaded a liveslak ISO file and want to boot that ISO directly from its location on your computer's hard drive, you can use this Grub configuration block and add it to your ''/boot/grub/grub.cfg'':<code> 
 +menuentry "LIVESLAK ISO" --class gnu-linux --class os --class icon-linux { 
 +  set iso='/data/ISOS/slackware64-live-xfce-current.iso' 
 +  set bootparms='load_ramdisk=1 prompt_ramdisk=0 rw printk.time=0 kbd=us tz=Europe/Amsterdam lang=nl' 
 +  
 +  search -f $iso --set=root 
 +  loopback loop $iso 
 +  linux (loop)/boot/generic livemedia=scandev:$iso $bootparms 
 +  initrd (loop)/boot/initrd.img 
 +}</code> 
 + 
 +This example will add a 'LIVESLAK ISO' menu entry to your local computer's boot menu, through which you can start a downloaded XFCE Live ISO pre-configured for a US keyboard, Dutch language and Amsterdam timezone.

 +
 +==== Using the Live OS to install Slackware to hard disk ====
 +
 +All variants of Slackware Live Edition contain a script "setup2hd", a tweaked version of the regular Slackware setup program.
 +The "setup2hd" script supports regular Slackware network installations. In addition it allows you to install the Slackware release on which the Live OS is based, to the computer's local hard disk.  You must boot the Live OS first, and then start ''setup2hd'' either in an X Terminal in your graphical Desktop Environment (aka Runlevel 4), or from the console in Runlevel 3.  The fact that you can start "setup2hd" from a graphical terminal means that during installation, you can continue browsing, listening to music, watching video, reading an e-book or whatever else makes you pass the time.
 +
 +The "setup2hd" script has some capabilities that the original Slackware 'setup' lacks:
 +  * It will launch fdisk/gdisk if you forgot to create Linux partitions in advance;
 +  * It will allow you to create a regular user account and set its password;
 +  * It will prompt you to set the root password in a graphical dialog.
 +
 +
 +==== Updating the kernel (and more) on a USB stick ====
 +
 +
 +A script is available which allows you to tweak the content of a USB Live stick.
 +
 +Specifically, the script is able to:
 +  * Upgrade the kernel and modules, making a backup of the old kernel and modules.
 +  * Restore the backed-up kernel and modules if the new kernel is not working.
 +  * Add network support modules for PXE boot (if missing).
 +  * Increase (or decrease) USB wait time during boot.
 +  * Replace the Live init script inside the initrd image with a new script that you supply.
 +  * Move current persistence data to a new squashfs module in 'addons' afther which the persistence store will be re-initialized.  The new module's name is time-stamped (/liveslak/addons/0099-slackware__customchanges-yymmddHHMMSS.sxz) so that this action can be repeated many times.
 +
 +The script is meant to be used while you are running Slackare Live from that same USB stick but this is not mandatory. With the exception of the '-p' option which moves the persistence data into a squashfs module, its functions can be used on any Linux computer where you can insert the USB stick. 
 +
 +Before making any modifications, the script will show you a prompt at which point you can evaluate whether it is safe to continue.
 +
 +This script, called 'upslak.sh', accepts the following parameters: <code>
 +  -b|--nobackup              Do not try to backup original kernel and modules.
 +  -d|--devices               List removable devices on this computer.
 +  -h|--help                  This help.
 +  -i|--init <filename>       Replacement init script.
 +  -k|--kernel <filename>     The kernel file (or package).
 +  -m|--kmoddir <name>        The kernel modules directory (or package).
 +  -n|--netsupport            Add network boot support if not yet present.
 +  -o|--outdev <filename>     The device name of your USB drive.
 +  -p|--persistence           Move persistent data into new Live module.
 +  -r|--restore               Restore previous kernel and modules.
 +  -s|--scan                  Scan for insertion of new USB device instead of
 +                             providing a devicename (using option '-o').
 +  -v|--verbose               Show verbose messages.
 +  -w|--wait<number>          Add <number> seconds wait time to initialize USB.
 +</code>
 +Examples:
 +
 +  * Get a listing of all available removable devices on the computer:
 +    # ./upslak.sh -d
 +  * Updating kernel and modules, providing two packages as input and assuming the USB stick is known as /dev/sdX:
 +    # ./upslak.sh -o /dev/sdX -m kernel-modules-4.19.0-x86_64-1.txz -k kernel-generic-4.19.0-x86_64-1.txz
 +  * Restore the previous kernel and modules after a failed update, and let the script scan your computer for the insertion of your USB stick:
 +    # ./upslak.sh -s -r
 +  * Replace the Live init script with the latest template taken from the git repository:
 +    # ./upslak.sh -o /dev/sdX -i liveslak/liveinit.tpl

 +
 +The "iso2usb.sh" script wipes and re-partitions the USB stick unless the "-r" or //refresh// parameter is used.  See section "[[#transfering_iso_content_to_usb_stick|Transfering ISO content to USB stick]]" for an explanation of all commandline switches. \\ The script will create 3 partitions:
 +
 +  * First partition: a small (1 MB in size) FAT partition which  is not used for Slackware Live Edition.  It can be used by an alternative bootloader if needed.  You can also store your LUKS keyfile on it to unlock a LUKS-encrypted Slackware Linux computer (see the [[http://ftp.osuosl.org/pub/slackware/slackware64-current/README_CRYPT.TXT|README_CRYPT.TXT]] file on your Slackware DVD for more information on LUKS keyfiles).
 +  * Second partition: a 100 MB VFAT partition containing the kernel, initrd and all the other stuff required by syslinux and grub2 to boot Slackware Live Edition.
 +  * Third partition: a Linux partition taking up all of the remaining space. It contains the actual liveslak modules, the persistent live storage and optionally your encrypted homedirectory. You can use the remainder of this Linux //ext4// filesystem's free space to store anything you like.
 +
 +Note that this script is the only supported method of transfering the liveslak ISO content to a USB stick and make that USB stick into a persistent live OS.  Several 3rd party tools (like multibootusb, rufus, unetbootin) that claim to be able to mix several Live OS'es on a single USB stick and make them all work in a multi-boot setup, are not currently supporting liveslak.

 +=== upslak.sh ===
 +
 +
 +The sixth script:
 +
 +The "upslak.sh" script's runtime usage is explained in detail in a previous paragraph "Updating the kernel (and more) on a USB stick".
 +
 +This section explains how the script modifies the content of the Live USB stick.
 +
 +When the script is started, it will do some sanity checks and then extracts the content of the initrd image. Some characteristics of the initrd will be recorded:
 +  * existence of previously backed-up kernel modules is checked,
 +  * template variables and their values are obtained from the init sctript,
 +  * the current USB wait time is checked.
 +Depending on the parameters passed to the script, it will then perform one or more of the following actions:
 +
 +== Update the kernel and moules ==
 +
 +You can provide a new kernel and its modules in two ways.  The '-k' option accepts a kernel image file or else a Slackware package contaning a kernel.  The '-m' option accepts a directory tree of modules below "/lib/modules/, or else a Slackware package containing kernel modules.
 +If there is sufficient space on the Linux and EFI partitions, the script will make a backup of the current kernel and modules by renaming the kernel and the module directory with a ".prev" suffix.  Sufficient space means that at least 10 MB of free space must remain on the partition(s) after making the backup and installing the new kernel plus modules. If space is an issue, you can skip making a backup by providing the '-b' parameter to the script (a possibly unsafe choice).
 +
 +== Restore backed-up kernel and modules ==
 +
 +If a backup was made of kernel and modules, the upslak.sh script is able to restore these using the '-r' option, thereby removing the replacements.  This comes in handy when the replacement kernel turns out to be non-functional.
 +
 +== Add network support modules ==
 +
 +This should normally not be needed.  By default, all liveslak ISO images have network support built-in.  But customized Live ISO images may be shipped without network support initially.  If you want your Live OS to be PXE-bootable you need network support in the kernel.  Use the '-n' option.
 +
 +== Increase (or decrease) USB wait time ==
 +
 +Similar to the functionality of the "iso2usb.sh" script, the "upslak.sh" script is able to alter the USB wait time at boot using the '-w' option.
 +
 +== Replace the liveslak init script ==
 +
 +The init script inside the initrd image is the core of liveslak.  The init script prepares the Live filesystem and configures several run-time OS parameters.  If you have made modifications to this init script you can easily replace the default init script with your own script using the '-i' option.  The "upslak.sh" script is smart enough to recognize a iveslak template as input.  The ".tpl" extension of some liveslak files means that these are templates.  They are not usable as-is, because they contain placeholder strings like "@VERSION@" or "@DISTRO@" that first need to be replaced with real values.  The "upslak.sh" script will take care of these substitutions.
 +
 +== Wrap persistence data into a new squashfs module ==
 +
 +Persistence data will accumulate over time on the USB stick.  That is perfectly OK, and you can wipe it on boot if that is needed.  But sometimes you want to capture the packages you installed into the persistent storage, and create a new squashfs module out of them.  The "upslak.sh" script is able to move your persistence data into a new squashfs module using the '-p' option.  The new module will be created in the "/liveslak/addons/" directory so that it will be loaded into the Live OS everytime your USB Live boots up.  After creating the new module, the persistence store will be re-initialized (i.e. its content will be erased on the next boot).  The new module's name is time-stamped (/liveslak/addons/0099-slackware_customchanges-yyyymmddHHMMSS.sxz where yyyymmddHHMMSS is the timestamp) so that this action can be repeated as many times as you want.

 +=== OS configuration file for persistent media ===
 +
 +If present, the liveslak init will load a OS config file from a persistent Live medium such as a USB stick.  In the case of //Slackware Live Edition// this file is called ''/liveslak/slackware_os.cfg'' - i.e. is placed in the "''liveslak''" directory of your USB drive.  For custom non-Slackware Live OS-es based on liveslak, the filename may be different.\\ This file contains one or more "VARIABLE=value" lines, where VARIABLE is one of the following variables that are used in the live init script:
 +  * BLACKLIST, KEYMAP, LIVE_HOSTNAME, LOAD, LOCALE, LUKSVOL, NOLOAD, RUNLEVEL, TWEAKS, TZ, XKB.
 +Values for the variables defined in this configuration file override the values already set via liveslak's own defaults or via boot-up command-line parameters.
 +
 +When booting your persistent //Slackware Live Edition//, the optional boot-time parameter "cfg" deals with this OS configuration file. The "cfg" parameter understands two possible argument values:
 +  * "cfg=write" will (over)write the OS configuration file to your USB drive, using the values for all of the above variables that are valid for that particular boot. So if your timezone is "''PST''" then one of the lines in that file will read "''TZ=PST''".
 +  * "cfg=skip" will skip processing of an existing "''/liveslak/slackware_os.cfg''" file.
 +
 +The OS configuration file is not present by default. You either create it at boot-time using "''cfg=write''" (which is a persistent change) or you create it manually using an ASCII text editor, after mounting the USB partition on a computer.  As an example, here is the content of "''/liveslak/slackware_os.cfg''" on my own USB stick: <code>
 +KEYMAP=nl
 +LIVE_HOSTNAME=zelazny
 +LOCALE=nl_NL.utf8
 +TWEAKS=tpb,syn
 +TZ=Europe/Amsterdam</code>

New SLAX releases are based on Debian.
  
 The Live functionality of SLAX is based on aufs and unionfs which requires a custom-built kernel with aufs support compiled-in.  It is small and has its boot scripts tweaked for startup speed. The Live functionality of SLAX is based on aufs and unionfs which requires a custom-built kernel with aufs support compiled-in.  It is small and has its boot scripts tweaked for startup speed.

 Porteus was created as a fork of SLAX by the SLAX community when the development of SLAX seemed to have ended.  Porteus has an active user community where it's "all about the modules" The use of aufs instead of overlayfs allows Porteus (like SLAX) to add and remove squashfs modules in the running Live system on the fly, which sparked the development of a lot of community modules.  It looks like the next generation of Porteus will be based on Arch Linux instead of Slackware: this has to do with the original Porteus developer leaving the team. Porteus was created as a fork of SLAX by the SLAX community when the development of SLAX seemed to have ended.  Porteus has an active user community where it's "all about the modules" The use of aufs instead of overlayfs allows Porteus (like SLAX) to add and remove squashfs modules in the running Live system on the fly, which sparked the development of a lot of community modules.  It looks like the next generation of Porteus will be based on Arch Linux instead of Slackware: this has to do with the original Porteus developer leaving the team.
