fc6 did a yum update, which upgraded to iputils 20070202-1.fc6 I didn't have rdisc running, and had it disabled in all runlevels the upgrade started it, which killed my network connectivity Looks like a script issue in the packaging
This issue should be fixed in iputils-20070202-2.fc6
It's not fixed [root@slartibartfast ~]# chkconfig --list rdisc rdisc 0:off 1:off 2:off 3:off 4:off 5:off 6:off [root@slartibartfast ~]# rdisc isn't running I do a yum update, which takes me from iputils-20070202-1.fc6 to iputils-20070202-3.fc6 rdisc gets started, with resultant network breakage....
During update process rpm first install new package and then remove the old one. IFAIK the last script executed during the update (in this case) is faulty %postun from iputils-20070202-1.fc6. The only way (i know of) how to avoid restarting rdisc daemon during update is to update iputils with rpm # rpm -Uvh --nopostun <path to>/iputils-20070202-3.fc6.rpm Update from version iputils-20070202-3 and above should work as required.
