So, chalk this up to another "I spent way too long trying to figure out why anaconda acts a certain way" type issue, but I just saw my first congratulations screen since kickstarting my own custom ES 4 installers. In previous versions (and maybe it was just AS 2.1), this worked fine in the %post section: /sbin/service network start /sbin/service portmap start ifconfig $ETH_ACTIVE $ip up /usr/sbin/ntpdate $NTPSERVER In ES 4, these commands somehow (haven't figured out how yet) cause the install to crash (throws a traceback referenced in previous email) after the post section has been run and before the congrats screen. I'm hoping this email will hopefully save someone else the agony I have just lived through trying to debug this. Btw - I was getting the same problems on two types of hardware doing PXE nfs installs, and the hardware checked out fine. Regards, Steve
