Comment 4 for bug 1939949

I've just noticed similar messages on a MAAS server:

"kernel: [8227300.867247] audit: type=1400 audit(1653363233.557:970746): apparmor="DENIED" operation="open" profile="snap.maas.supervisor" name="/dev/vda" pid=1645448 comm="amd64" requested_mask="r" denied_mask="r" fsuid=0 ouid=0"

"vda" is the root (and only) disk on this particular machine.

We're also seeing this for "/etc/gss/mech.d/":
jsimpso@maas:~$ grep 'apparmor="DENIED"' /var/log/syslog | cut -d ' ' -f 12,13 | sort | uniq
profile="snap.maas.supervisor" name="/dev/vda"
profile="snap.maas.supervisor" name="/etc/gss/mech.d/"

Here's the output of "snap connections maas" as previously requested:
