Yes, there's been fairly extensive changes in cgroups recently. I'm
not seeing these tests fail though - probably cos I'm not running on
machines without cgroup support.

This subtree is populated when cgroup subsystems exist - I guess these
are older kernels with no cgroups? (hmm I wonder if this is the right
error code for this situation?).
One part of the last round of changes was to make cgroup.groups. the
dynamic non-leaf PMNS entry, whereas previously it was cgroup. - and
that was *always* populated with the cgroup.mounts and cgroup.subsys
(fixed) hierarchies. Could be some latent issue with dynamic names?
Or maybe I've just (ab)used them in a new way.
I notice mmv always does this "pre-populate with a few fixed names"
for its dynamic namespace use, and the Linux kernel interrupt names
(also dynamic) will always have a starting set... hmmm.
cheers.
