UEFI boot the easy way
I recently had a requirement for a small secure and complete Linux on a USB stick. In order to make it "future proof" the usb should be UEFI bootable. And as regular backups are needed the system should be a small as possible.
So after weeks of trial and error I discovered this:
In order to make the USB UEFI bootable issue the command:
export USE_EFI=YES
before running setup-alpine.
Shrinking the root partition was slightly more complex. Edit the "/sbin/setup-disk" script and change line 970 ( or thereabouts ) from:
local root_size=
to:
local root_size=${ROOT_SIZE}
Then
export SWAP_SIZE=0 export ROOT_SIZE=750
Before running setup-alpine as normal.
Then you have a less than 1GB fully fuctioning command line Linux which is boots UEFI only.
The setup script creates an annoying dummy swap file in /dev/sdX2 which can be safely removed.
