Can you pick one process you expect to see the lxc output for and send me
the output of /proc/<PID>/cgroup ?
Hi Craig,
The lxc/lxd folks have not changed the default lxc prefix since release
4.0.0 (now at 4.0.6). But in that release they restored the configure
option:
--with_cgroup_pattern=
I wonder if Andreas exploited that provision. If so, perhaps by keeping
the default pattern and just adding their own prefix the problem may be
solved.
I have in ind something like this:
--with_cgroup_pattern=MY-PFX.lxc.payload.
( note the trailing '.', although '/' would work just as well )
On the other hand, if Andreas didn't re-build lxc, I think we're
screwed. I know of no way to extract an altered cgroup pattern at runtime.
Regards,
Jim
