Just to make sure - did you reload the policy after this? > [ 2828.314451] type=1400 audit(1346445533.683:25): apparmor="DENIED" > operation="mount" info="failed type match" error=-13 parent=5073 profile="lxc- > container-default" name="/mnt/wxdata/" pid=5074 comm="mount.cifs" > fstype="cifs" srcname="//192.168.0.10/Share" flags="rw" I haven't tried this, but it sure looks like this should be fixed with your rule. > Short of turning apparmor off, which is my next step... Well it's certainly worth trying turning apparmor off (just with lxc.aa_profile = unconfined) to make sure it's the problem. The network filesystems are still persnickity in containers, and I'm not even sure cifs will work at all. > Any apparmor guru's know how to remove this block ? ? ? > > Or is this hidden in some other file now since the container is created? ? > > And I would prefer not to use fuse to do this, for my own reason(s). > > Thanks. > > ------------------------------------------------------------------------------ > Live Security Virtual Conference > Exclusive live event will cover all the ways today's security and > threat landscape has changed and how IT managers can respond.
