[pve-devel] [PATCH docs] firmware: adapt to proxmox packaged fwupd

[Stoiko Ivanov]

We ship our own fwupd package, since it needs to handle the
differently named efi_os_dir (proxmox vs debian).
Due to our experience with `udisks2` causing issues on hypervisors,
our package downgraded the Recommends udisks2, to a Suggests.
The downside is, that users need to explicitly set their ESP
mountpoint in the config file.

Additionally a minor stylistic rephrasing (is an option vs. could be
an option).

Tested this today, while giving our fwupd package a spin.

+Since {pve} ships its own version of the `fwupd` package, for Secure Boot
+Support with the Proxmox signing key, which does not recommend the `udisks2`
+package, due to observed issues with its use on hypervisors setting the mount
+point of the EFI partition in `/etc/fwupd/daemon.conf` is necessary:

+.File `/etc/fwupd/daemon.conf`

+# Override the location used for the EFI system partition (ESP) path.

 TIP: If the update instructions require a host reboot, make sure that it can be
 done safely. See also xref:ha_manager_node_maintenance[Node Maintenance].
