Comment 4 for bug 1043018

Yeah, the hang only happens on users with nfs home directories.
I should file a separate bug for that.

Even on users with a local home directory, though, lxc-ls lists containers multiple times
after starting and logging into a container. For instance,

$ lxc-ls
demo_ubuntu_1204
demo_ubuntu_1204
$ bash -x /usr/bin/lxc-ls
+ lxcpath=/var/lib/lxc
+ '[' '!' -r /var/lib/lxc ']'
+ ls -- /var/lib/lxc
demo_ubuntu_1204
++ netstat -xa
++ grep /var/lib/lxc
++ sed -e 's#.*/var/lib/lxc/\(.*\)/command#\1#'
+ active=demo_ubuntu_1204
+ test -n demo_ubuntu_1204
+ get_cgroup
+ local mount_string
++ mount -t cgroup
++ grep -E -e '^lxc '
+ mount_string=
+ test -n ''
++ grep -m1 -E '^[^ \t]+[ \t]+[^ \t]+[ \t]+cgroup' /proc/self/mounts
+ mount_string='cgroup /sys/fs/cgroup/cpuset cgroup rw,relatime,cpuset,clone_children 0 0'
+ test -z 'cgroup /sys/fs/cgroup/cpuset cgroup rw,relatime,cpuset,clone_children 0 0'
++ echo 'cgroup /sys/fs/cgroup/cpuset cgroup rw,relatime,cpuset,clone_children 0 0'
++ cut '-d ' -f2
+ mount_point=/sys/fs/cgroup/cpuset
+ test -n /sys/fs/cgroup/cpuset
++ cat /proc/1/cgroup
++ awk -F: '{ print $3 }'
++ head -1
+ init_cgroup=/
+ cd /sys/fs/cgroup/cpuset///lxc
+ ls -d -- demo_ubuntu_1204
demo_ubuntu_1204

So one copy is coming from the ls of /var/lib/lxc, the other is coming from netstat -xa.

Why the two paths?
