<del>Ideally, gummiboot [systemd-boot] should be replaced by grub2 now that it has been consumed by systemd.

Hopefully I'm putting this in the correct spot, but I for one would also like to see instructions on configuring a UEFI bootable USB assuming there's already a boot manager such as rEFInd on the target system.[[User:Siernan|Regards, Siernan]] ([[User talk:Siernan|talk]]) 23:13, 14 August 2017 (UTC)

== 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.
