Nothing beyond guesswork, since it's been a while since I've played
with LXC. In any case, I was struggling a bit for the correct
terminology.
Am I similarly off-base with regards to the chroot'd scenario?
chroot case is going to be reachable from namespace root, but I seriously
doubt that pathname relative to that will be more useful...
Again, relying on pathnames for forensics (or security in general) is
a serious mistake (cue unprintable comments about apparmor and similar
varieties of snake oil). And using audit as poor man's ktrace analog
is... misguided, to put it very mildly.
