[pve-devel] [PATCH v2 quincy-stable-8 ceph 03/11] debian: add patch to fix ceph crash dir permissions in postinst hook

[Max Carrara]

Ceph has a postinst hook that sets the ownership of '/var/lib/ceph/*'
to ceph:ceph (in our case), but misses out on '/var/lib/ceph/crash/posted'.

This patch therefore also updates the permissions of '/var/lib/ceph/*/*'.

Changes v1 --> v2:
  * use `find` instead of for-loop

+Subject: [PATCH] debian: adjust permissions of subdirectories of /var/lib/ceph
+
+A rather recent PR made ceph-crash run as "ceph" user instead of
+root [0]. However, because /var/lib/ceph/crash/posted belongs to root,
+ceph-crash cannot actually post any crash logs now.
+
+This commit fixes this by also updating the permissions of
+/var/lib/ceph/*/* - the subdirectories and files of the directories in
+/var/lib/ceph - by using `find` instead of a loop over a glob pattern.
