[Bug 1166870] [NEW] lxc-clone fails silently

[James Hunt]

Public bug reported:

$ sudo lxc-clone -o old -n new
$ echo $?
1
$ sudo bash /usr/bin/lxc-clone -o old -n new
Tweaking configuration
Copying rootfs...
Updating rootfs...
'raring-cloned' created
$

Problem appears to be missing "|| true" in LXC_PATH= assignment in
/usr/share/lxc/lxc.functions:

LXC_PATH=$(grep -v "^#" "$globalconf" 2>/dev/null | grep "[ \t]*lxcpath[
\t]*=")

The above can fail due to running via 'set -e' so needs to be something
like:

LXC_PATH=$(grep -v "^#" "$globalconf" 2>/dev/null | grep "[ \t]*lxcpath[
\t]*=" || true)

** Affects: lxc (Ubuntu)

         Status: Triaged
