Rudder

Running on a Debian squeeze, /opt/rudder/bin/check-rudder-agent fails with this output from 'bash -x':

+ check_and_fix_cfengine_processes
++ ps -h -o utsns --pid 30877
+ ns=
jclarke@hostname:~$ echo $?
1

This comes from the following line:

 67   # Detect the correct ps tool to use
 68   ns=$(ps -h -o utsns --pid $$ 2>/dev/null)

I found this in 3.1.3 but it goes as far back as the 2.11 branch.

This was apparently introduced in #7189 and seems to be related to #7245, #7243.
