 If you say so.

 Yes

 I do run dhcpd as root and without paranoia, so I question this claim. If 
 the daemon changes its uid for security purposes, I have no objection 
 (although there is no mention of this on the man page) but why not fill in 
 /var/run as documented before dropping priviledges?

 No need for anything so elaborate. You could just add a fourth file path 
 to the list of files used.
 
 Thanks for having a look. It isn't a big deal and I thought I was helping.
