[pve-devel] [PATCH manager 1/2] fix #6779: pveupdate: renew already expired certificates

[Fabian Grünbichler]

if nodes are offline for a longer period of time, they might not be renewed by
pveupdate before they expire. the `verify` call here just serves as an
extra safeguard to prevent accidental overwriting of certificates not actually
signed by the cluster CA, checking the expiry time servers no purpose.

verified by manually creating an expired and a soon-to-be-expired certificate..
