[pve-devel] [PATCH 2/3] proxmox-boot: warn on missing systemd-boot package

[Stoiko Ivanov <s.ivanov@proxmox.com>]

With the shipping of systemd-boot as separate package, we cannot rely
on `bootctl` being present in all systems (e.g. currently all systems
upgraded from PVE 7 will not automatically pull systemd-boot in.

This patch adds a check for existence + warning with an explanation to
the only invocation of bootctl in the boot-tool codebase
