Ah, I see the problem. This is fix released in quantal, but is still
broken in precise. The fix is to switch 'netstat -xa' with 'netstat
-xl'. We'll get that SRU'd.
Thanks again for the bug report.

** Description changed:
+ ====================
+ SRU Justification:
+ 1. Impact: lxc-ls output can have duplicates.
+ 2. Development fix: use 'netstat -xl' in place of 'netstat -xa' to only show
listening sockets
+ 3. Stable fix: same as development fix
+ 4. Test case: start a container, open a second console (with lxc-console -n
<containername>). Then do 'lxc-ls' and look for duplicate entries in the
second line.
+ 5. Regression potential: none.

This seems wrong:

Lessee: lxc-ls does
active=$(netstat -xa 2>/dev/null | grep $lxcpath | \
- sed -e 's#.*'"$lxcpath/"'\(.*\)/command#\1#');
+ sed -e 's#.*'"$lxcpath/"'\(.*\)/command#\1#');
which expands to
++ netstat -xa
++ grep /var/lib/lxc
++ sed -e 's#.*/var/lib/lxc/\(.*\)/command#\1#'

- So, perhaps that should be grep "LISTENING.*$lxcpath" ?
