Bug#1109098: systemd-boot: installed initramfs post-update hook assumes kernel images are compressed

[Evgeni Dimitrov]

Package: systemd-boot
Version: 257.7-1
Severity: important
X-Debbugs-Cc: evgeni.dimitrov at gmail.com

Dear Maintainer,

This package installs an initramfs hook in /etc/initramfs/post-update.d/systemd-boot
which refers to "/boot/vmlinuz-*", however on riscv64 the kernel images
are uncompressed and named "/boot/vmlinux-*".

Predicatably, this causes errors during update-initramfs operations.

update-initramfs: Generating /boot/initrd.img-6.12.35+deb13-riscv64
Updating kernel version 6.12.35+deb13-riscv64 in systemd-boot...
Failed to open kernel image file '/boot/vmlinuz-6.12.35+deb13-riscv64': No such file or directory
run-parts: /etc/initramfs/post-update.d//systemd-boot exited with return code 1

See below for an example fix, which seems to work for me.
