Hmm. They are running 3-4 odd finds:
nobody 11509 0.0 0.3 832 492 ? D May 28 0:00 find / ( -fstype
nfs -o -fstype NFS -o -fstype afs -o -fstype proc -o -fstype smbfs -o
-fstype autofs -o -type d -regex
Nobody's /etc/passwd entry looks sane
I wonder if this is some odd YaST process trying to mount a SuSE cdrom, or
find some rpm's to examine?
