I was initially not sure that was going to be relevant after all, because I was expecting AppArmor to be a thing that has to be constantly running in order to be effective, and there's no such process visible that I can see - but apparmor shows up in dmesg, et cetera, so I must have been expecting wrong. > The change to mountkernfs was ineffective on your system for the same > reason it was ineffective on mine, but the apparmor workaround means > you don't see the effects since apparmor has got it mounted by the > time you log in.

Heh. That line was a leftover of when I was going to raise the question of why the "fstype not available" test was even being reached, given the "already mounted" test, before I realized that it must be simply a matter of test order. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
