Created attachment 187621 [details] Log after boot.
Comment 2 George Beshers 2007-09-06 09:52:19 EDT
Just an update. Binary search of patches didn't work because when I build the kernel with my build script the problem doesn't occur, but I confirmed that with the kernels in the snapshots it does. I am now doing an rpmbuild to see if that kernel works and to get a trace to see what the differences are in the build process.
Comment 3 George Beshers 2007-09-06 18:40:19 EDT
Sigh... Nothing to do with the kernel. The problem is that in snap3 and snap4 /etc/sysconf/network does not get a GATEWAY entry. Not sure if this is related to the number of devices or if there is something else going on. The system where the problems occur has 8 ports with 6 active and 4 connected all to the same subnet: inet addr:184.108.40.206 Bcast:220.127.116.11 Mask:255.255.255.0 inet addr:18.104.22.168 Bcast:22.214.171.124 Mask:255.255.255.0 inet addr:126.96.36.199 Bcast:188.8.131.52 Mask:255.255.255.0 inet addr:184.108.40.206 Bcast:220.127.116.11 Mask:255.255.255.0 inet addr:127.0.0.1 Mask:255.0.0.0 The following is probably a decent clue, note that /mnt/sda10 is the root of the snap2 install: [root@billberry1 ~]# diff -r -q /etc/sysconfig/ /mnt/sda10/etc/sysconfig/ Only in /etc/sysconfig/: dhcpd Only in /etc/sysconfig/: dhcrelay Only in /mnt/sda10/etc/sysconfig/networking/devices: ifcfg-eth0 Only in /mnt/sda10/etc/sysconfig/networking/profiles/default: hosts Only in /mnt/sda10/etc/sysconfig/networking/profiles/default: ifcfg-eth0 Only in /mnt/sda10/etc/sysconfig/networking/profiles/default: network Only in /mnt/sda10/etc/sysconfig/networking/profiles/default: resolv.conf Only in /etc/sysconfig/: spamassassin

Pretty sure notting takes care of all initscripts related stuff.
Comment 5 Bill Nottingham 2007-09-10 16:39:48 EDT
anaconda writes /etc/sysconfig/network.
