My guess is that when you started dhcpd first time, it copied 
"/etc/subnets" as instructed - but next time it didn't because 
/etc/subnets already exists in /var/lib/dhcp.

Try setting DHCPD_CONF_INCLUDE_FILES="/etc/dhcpsubnets/*" and see if 
that does it.

Alternatively, unset that, and create a symlink so that 
/etc/dhcpsubnets is a symlink to /var/lib/dhcp/etc/subnets. Ie, you 
edit the file 'in place' where dhcpd is looking for them, but have an 
easy to remember pointer to them.
