### Prerequisites
This tool expects that you already set up snapper. It also expects that each
snapshots linux and initramfs files (`/boot/vmlinuz-linux` and
`/boot/initramfs-linux.img`) as well as a kernel command line file
(`/etc/snap-pac-uki/kernel-cmd`) are available within each snapshot.
While not depending on it directly, this tool expects that you already set up
snapper. It expects, that each snapshot contains its kernel
(`/boot/vmlinuz-linux`) and initramfs (`/boot/intitramfs-linux.img`), as well as
a kernel command line file (`/etc/snap-pac-uki/kernel-cmd`).
The fallback initramfs (`/boot/initramfs-linux-fallback.img`) and fallback
command line file (`/etc/snap-pac-uki/kernel-cmd-fallback`) are only required
on the current system.
For generating the current and fallback UKIs, the kernel and initramfs files of
the currently running system are used. For a kernel cmd, it uses
`/etc/snap-pac-uki/kernel-cmd-current` and `/etc/snap-pac-uki/kernel-cmd-fallback`.
Also the current command line file (`/etc/snap-pac-uki/kernel-cmd-current`)
needs is only required on the current system.
EFI boot options are only created for each snapshot. If you want the UKIs
created for the current system, you'll need to add boot entries yourself:
If you want to boot a UKI directly, use the `efibootmgr` command to create an
entry.
