A system had a disk problem, I took out the disk, mounted on another system, tweaked around until I thought the disk problem was fixed, then put it back in the original system. I did not edit any config files among the tweaks. When I booted the system, NIS was not working right. I found that these files had been changed: /etc/yp.conf /etc/resolv.conf /etc/ntp.conf /etc/auto.master /etc/hosts.allow. A comment in the new bogus yp.conf indicated it had been created by NetworkManager. But Networkmanager is not active:

# chkconfig --list|grep -i netw NetworkManager 0:off 1:off 2:off 3:off 4:off 5:off 6:off network 0:off 1:off 2:on 3:on 4:on 5:on 6:off

Did hald or something like that run some NetworkManager stuff? How could this happen, or rather, how do I prevent this from ever happening again?

mahalo, Dave
