Sorry for the duplicate - I had earlier posted to the list from the
wrong email identity and presumed it would be rejected as coming from a
non-subscriber but looks like it has just been waved through now.
The immediate problem was solved - I needed to add an additional
"chris:1000:1" to /etc/sub{u,g}id

I'm following the guide to run X apps in a container at:

As a starting point, I have a normal unprivileged container running
perfectly. However when I change the id_map configuration to look like:
lxc.id_map = u 0 100000 1000
lxc.id_map = g 0 100000 1000
lxc.id_map = u 1000 1000 1
lxc.id_map = g 1000 1000 1
lxc.id_map = u 1001 101001 64535
lxc.id_map = g 1001 101001 64535
the container fails to start, claiming:
chris@d6:~/.local/share/lxc$ lxc-start -n x11-test-x86_64 -F
newuidmap: uid range [1000-1001) -> [1000-1001) not allowed
lxc-start: start.c: lxc_spawn: 1161 failed to set up id mapping
...
...
Sure enough, if I comment out the lines:
lxc.id_map = u 1000 1000 1
lxc.id_map = g 1000 1000 1
the container runs again - but it's that particular mapping that is
needed in this case.
I set up a log file to priority DEBUG but no extra clues there - it just
says the same thing.
I'm using:
lxc-2.0.1
cgmanager-0.39
with container config file attached.
Can anyone shed light on this problem please?
