OK, here is a better guess. cfengine seems to match against the full 
line "ps auxw" or similar returns. In my case for syslog-ng, that line 
looks like this:

syslog   12067  0.0  0.0  1748  868 ?        S    Sep18   0:00 
/usr/sbin/syslog-ng -u syslog -g audit

or

syslog   12067  0.0  0.0  1748  868 ?        S    Sep18   0:00 syslog-ng 
-u syslog -g audit

All on one line of course.

So the regexp I ended up using is:

"[0-9]:[0-9][0-9] [^ ]*syslog-ng "

I use the time information before ARGV[0] as an anchor. Another 
possibility would be some regexp that tries to fetch all the field 
before ARGV[0] to make sure there is no match of that regexp after ARGV[0].

All of which aren't really nice.
