That depends. What are you really wanting to achieve? Might your problem
be better solved by looking at the dhcp leases file instead, or are you
really just interested in the logs?

search.cpan.org reveals Net::ISC::DHCPd and Text::DHCPLeases as possible
candidates for inclusion.

You could also include something like 'tail --follow=name'.

If you are worried about log rotation, it would probably be better to
hook into logrotate's pre/postrotate mechanism.

You would need to do something intelligent if syslogd were to restart
(eg. because of an update). You would also need to make sure that your
script started after syslogd.
