Would indeed better match the currently used /run/pve ownership.

You can use dh_installtmpfiles [0] for this and just add the relevant config in
a "debian/package.tmpfiles" file. With debhelper compat level 13 that helper
will be run by default [1], and as level 13 is the recommended level for Trixie,
I plan to switch all packages over to that anyway.

0: https://manpages.debian.org/trixie/debhelper/dh_installtmpfiles.1.en.html
1: https://manpages.debian.org/testing/debhelper/debhelper-compat-upgrade-checklist.7.en.html#v13
