From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.2.18 i686) When upgrading from 6.2 to 7.0, the upgrade of dhcpcd left me with no /var/lib/dhcp/dhcpd.leases. This causes /etc/rc.d/init.d/dhcpd start (or restart) to silently fail (silently in that I saw nothing reported in e.g. /var/log/messages). I diagnosed the problem by set -x at the top of the script and noted failure at the line: [ -f /var/lib/dhcp/dhcpd.leases ] || exit 0 When I touched the file and restarted again, everything went perfectly. Note that this is awfully hard to reproduce for me personally without re-upgrading my server, so I'll skip the next steps. I will say that the server was working perfectly immediately before and (once I touched /var/lib/dhcp/dhcpd.leases) immediately after the upgrade, so it is almost certain that removing the old dhcpd rpm removed the lease and installing the new one failed to touch/preserve/recreate it. Reproducible: Didn't try Steps to Reproduce: 1. Can only reproduce by re-upgrading system, but circumstances make it fairly certain that it is a bug in the upgrade process. 2. 3. This is a simple one to fix. Add a "touch /var/lib/dhcp/dhcpd.leases" to the %post of the rpm. This is harmless -- it preserves what is there for a functional upgrade and creates the file for a new or distribution revision upgrade. A second suggestion might be to put SOMETHING a bit more constructive in /etc/rc.d/init.d/dhcpd -- perhaps something like: [ -f /usr/sbin/dhcpd ] || echo "dhcpd not installed";exit 0 [ -f /etc/dhcpd.conf ] || echo "/etc/dhcpd.conf not installed";exit 0 [ -f /var/lib/dhcp/dhcpd.leases ] || touch /var/lib/dhcp/dhcpd.leases since there is really no reason to punt if the leases file doesn't exist -- just create it and go. Or at least announce what's wrong if you're going to punt.
