Re: SLES10 SP1 upgrade experiences
Addendum: There were cron jobs in /etc/cron.daily which we had disabled by renaming the script files to begin with a '#' character. The upgrade to SP1 left the disabled scripts in place, but installed new versions which are identical to the old ones which were disabled. I simply removed the new versions. suse-clean_catman suse-do_mandb suse.de-backup-rc.config suse.de-check-battery Also, the SP1 upgrade seems to have blanked out the relayhost directive in /etc/postfix/main.cf.
