Public bug reported:
As I understand it, lttng shouldn't be used out of the box - I'm seeing
apparmor complaining about it, though. The other aspect of it is the fact that
it's using a folder apparmor won't allow under snap confinement.
I realize this is a hybrid bug, but I don't know exactly what to expect for
either of these, I'm really filing it based on the symptoms for now.
$ snap install dekko --edge --devmode
$ snappy-debug.security scanlog &
$ /snap/bin/dekko
Log: apparmor="ALLOWED" operation="open" profile="snap.dekko.dekko"
name="/dev/shm/lttng-ust-wait-6-1000" pid=3230 comm="QQmlThread"
requested_mask="r" denied_mask="r" fsuid=1000 ouid=1000
Dekko doesn't link to lttng:
$ ldd /snap/dekko/current/usr/bin/dekko | grep lttng
