[pve-devel] [PATCH v3 cluster 3/4] pvecm: updatecerts: silence warning that potentially has no context

[Fiona Ebner <f.ebner@proxmox.com>]

If timeout is reached, run_fork_with_timeout will warn "got timeout".
When processing triggers for pve-manager (because of ExecStartPre of
pveproxy.service invoking pvecm updatecerts) that warning can appear
in the apt output without any context (output of the forked sub
doesn't appear there). So make sure to silence it, if the silent param
is set.

No changes in v3.
New in v2.

Can't use a normal if here, because of the 'local'.
