Bootstrap Alpine from Ubuntu (Magic Stick)

Today I spent quite a few hours trying to bootstrap alpine linux on my asus t100ta from ubuntu on the magic stick.

Here is my partitioning layout:

/dev/mmcblk0p1  /mnt/boot/esp  vfat  # ESP
/dev/mmcblk0p2  /mnt/boot      vfat  # Grub Boot
/dev/mmcblk0p3  /mnt           ext4  # Alpine Linux Root

• Asus T100 - 32-bit efi
• XDA - Asus T100TA Magic Stick

Alpine Linux Wiki Links

• Bootable USB
• Chroot Install
• Dualboot HDD Install
• Native HDD Install
• UEFI Boot USB

I am having issues with installing grub.

t100:~# apk add grub
ERROR: unsatisfiable constraints:
  grub (missing):
    required by: world[grub]
t100:~# 

I also cannot find a instructions on how to compile a new kernel. The Wiki page for that is blank.

I do not own the charging cable that came with this tablet, and while a regular phone charger will work, I cannot use the tablet and charge it concurrently, as the battery is drained faster than it is being charged.

Once I have this working, I will build an installer script to simplify the process.
