Public bug reported:
Running lxc-stop on a container which doesn't exist actually creates the
container, and messes up its permissions, causing sequences like:
$ lxc-stop -n foo && lxc-destroy -n foo && lxc-clone clean-machine foo
..to fail with bad errors:
# it definitely doesn't exist to start with:
% lxc-ls foo
% lxc-info -n foo
foo doesn't exist
% ls ~/.local/share/lxc/foo -al
ls: cannot access /home/faux/.local/share/lxc/foo: No such file or directory
# now let's stop it:
% lxc-stop -n foo
foo is not running
# tooling still thinks it doesn't exist:
% lxc-ls foo
% lxc-info -n foo
foo doesn't exist
# .. but there are some files!
% ls ~/.local/share/lxc/foo -al
total 0
drwxr-xr-x 1 faux faux 14 Jul 23 09:45 .
drwxr-xr-x 1 faux faux 8070 Jul 23 09:45 ..
-rw-rw-r-- 1 faux faux 0 Jul 23 09:45 foo.log
# and now lxc-clone is totally broken:
% lxc-clone base foo
lxc_container: lxccontainer.c: lxcapi_clone: 2707 Permission denied - open
/home/faux/.local/share/lxc/foo/config
clone failed
Can we worked around by manually rm -rfing ~/.local/share/lxc/foo.
