One suggestion I have seen is a cron job that tests if dhcpd.conf has
been updated, checks the syntax of the file and restarts dhcpd. Set
this up to run, say, every 30 minutes (or 15 or whatever you require).
That way you can reduce the number of restarts and aggregate all the
changes very simply. If you have multiple dhcp servers then set their
crons to restart dhcpd at different times.
5 minutes might occasionally be a bit too frequent for very large
numbers of leases as the systems may not have finished synchronising
before you stop and start.
