TO Do

• /boot/grub/grub.cfg needs to be tweaked to point to SLKroot
• /etc/defaults/grub needs GRUB_ENABLE_LINUX_LABEL=true added
• don't version number Slackware's GRUB entry - e.g. '/boot/efi/EFI/slackware-15.0+/grubaa64.efi'
• grub-mkconfig - potentially patch to prevent use, with option to override. - eg /sbin/mkinitrd is not implemented on ARM. See os-initrd-mgr(8) for details.
• Flashing tool - look at creating a microroot function within the sdcards.build that processes the os initrd

 partition  used for               filesystem FS label    installer mount point
 1          EFI boot?              fat32      SLKins_efi   ? shouldn't need one?
            * Requires GPT partition table

 2          /boot/GRUB's config    ext4       SLKins_boot  ?  ""
            that loads Slackware
            Installer.

            /assets/firmware/lxwhatever
            Add in the firmware here which can be flashed from within the installer
            using a post install script.
            It diverges from the rk3399, so let's hold the idea for now, but it's probably
            along the right lines.

. User DD's sd card SPI flash image:
    Flashes EFI firmware to SPI flash.

2. User dd's Slackware installer image to SD card.
3. Boots Honeycomb from SD card, boots Slackware installer.

4. User creates EFI partition , swap and OS and whatever partitions.

5. Installs Slackware to SSD on SATA
6. Reboots, removes SD card.
7. User makes honeycomb boot from SATA to boot OS.

8. First boot will find the SATA drive at SLKroot
9. and the swap at SLKswap0
10. and /boot/efi at SLKefi

SD Notes:
* SLKins_efi and SLKins_boot are not relevant at this point.
* The SD card can be removed and the system can run without it.

SATA Drive notes:
* The /boot/efi paritition needs to be labeled as SLKefi
* Rootdisk / needs to be labeled SLKroot
* If it exists, the swap should be named SLKswap0
* Grub finds the boot directory on root disk
* Grub boots the system ``
