Description:
some scripts (cron, snmpd, ...) in /etc/rc.d/ use pidof for finding process pid.
but with lxc, all lxc process are visible in the host.

Additional info:
lxc Linux Containers : http://lxc.sourceforge.net/
aur/lxc-git version: 0.7.2

Steps to reproduce:
exemple in /etc/rc.d/crond : PID=$(pidof -o %PPID /usr/sbin/crond)
when crond is running, pidof return only the good pid.
but when crond is not running, this command return all pid of crond, including lxc process and crond can't start

# lxc-ps faxu |grep crond
root 5556 0.0 0.0 5944 708 ? Ss Aug28 0:01 /usr/sbin/crond -S -l info
mx root 5112 0.0 0.0 5944 632 ? Ss Aug28 0:00 \_ /usr/sbin/crond -S -l info
ns1 root 8470 0.0 0.0 5944 456 ? Ss Aug28 0:00 \_ /usr/sbin/crond -S -l info

# echo $(pidof -o %PPID /usr/sbin/crond)
5556
# /etc/rc.d/crond stop
:: Stopping Cron Daemon [DONE]
# echo $(pidof -o %PPID /usr/sbin/crond)
8470 5112
# /etc/rc.d/crond start
:: Stopping Cron Daemon [FAIL]

Path attached : /etc/rc.d/functions.d/check_lxc_pid
this script remove pid of lxc process, and all /etc/rc.d/ work fine.
not fully tested.

sorry for my bad english
