NetBSD main.LAN 6.1.3 NetBSD 6.1.3 (GENERIC) i386
>Description:
In a stock install, /var/db/dhcpd.leases is not present, and is not created 
from /etc/rc.d/dhcpd (for instance). 

This causes dhcpd not to run, when enabling it in rc.conf.

I guess this is a design decision; the obvious thing to do is to touch 
/var/db/dhcpd.leases, and indeed this behaviour is documented in 
dhcpd.leases(5). 

However, it may cause unnecessary confusion for new users when enabling dhcpd 
with a valid config-file, and perhaps it is acceptable to let /etc/rc.d/dhcpd 
touch the leases-file if it didn't yet exist.
>How-To-Repeat:
1) install clean 6.1.3
2) create a valid /etc/dhcpd.conf
3) enable dhcpd in /etc/rc.conf: 'dhcpd=YES'
4) start dhcpd: '/etc/rc.d/dhcpd start'
5) dhcpd does not run
>Fix:
# touch /var/db/dhcpd.leases
