On arch it isn't particularly difficult to create UKIs other than changing like 2 lines in `mkinitcpio`'s config.

Then there is also `ukify` by systemd which also can create UKIs, which then can be installed with `kernel-install`, but that is a bit more work to set up than for `mkinitcpio`.

The main part is the signing, which I usually have `sbctl` handle.
