[pve-devel] [PATCH pve-kernel-meta v2 4/4] proxmox-boot: add pin/unpin functionality for non-p-b-t systems

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

While running `update-grub` directly in this case is a divergence from
the semantics of the command when p-b-t handles booting it makes the
cleanup in the `next-boot` case a bit tidier.
