Rootkit Hunter

I have a machine with an extra user with root privileges, for legitimate
reasons. I have patched
rkhunter by hand to whitelist the extra user, in this case called pepper,
by altering line 4928:

users_with_uid0=`grep -v '^:0:0:::' ${ROOTDIR}etc/passwd | grep ":0:" |
cut -d ":" -f1,3 | grep '0' | grep -vE '(root|pepper):0'`

of PROGRAM_version="1.2.9".

Of course it would be nicer to make a whitelist entry in the config file
instead of altering the rkhunter script, but I don't know how to do that.
