### Path fun.  Older versions of DHCP were installed in /usr/sbin, so we

### the user configures an alternate value).  LOCALSTATEDIR is totally
### braindead.  No one uses /usr/local/var/db/ nor /usr/local/var/run, and
### they would be insane for suggesting it.  We need to look in /var/for
### 'db' and 'state/dhcp' for db files, and /var/run for pid files by
### default.
