Subject: postinst: avoid spawning subshell
X-Git-Url: https://git.proxmox.com/?p=pve-storage.git;a=commitdiff_plain;h=cd48e1632c67c1a40be64d03ff3803ed38f3a930

postinst: avoid spawning subshell

which makes the continue not behave as intended.

Reported by shellcheck: SC2106: This [i.e. continue] only exits the subshell
caused by the (..) group

Also factor out long message for readability.
