Rudder

Hello,

When running the agent, I get on some servers:

# /opt/rudder/bin/rudder agent check
grep: : No such file or directory

# /opt/rudder/bin/rudder agent check -i
grep: -i: No such file or directory

Here is a few more informations :

# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 8.6 (jessie)
Release:        8.6
Codename:       jessie

# dpkg -l|grep rudder-agent
ii  rudder-agent                   4.0.1-jessie0               amd64        Configuration management and audit tool - agent

It seems to be related to the rerouting of stderr in /opt/rudder/share/lib/common.sh line 2:

# Warn on potentially invalid arguments
if grep -- -- "$*" > /dev/null

Thanks.
