dhcpd uses syslog to do the logging, so you need to be able to convince
syslog to work in the way you want.

I can think of two possibilities (both untested by me) :

1. use a log-facility statement inside each pool to specify a different
syslog destination. Typically you would use local0 through local7. You
will also need the appropriate log statement to actuially log the
information. A quick read of the dhcpd.conf man page suggests that this
might not work, since it doesn't start using the new syslog setting
until it has parsed the whole dhcpd.conf file. Also you are limited to
how many syslog facilities you can use.

2. this one depends on your syslog operation. If you can convince
syslog to use a different file for each priority within a given
facility then you could specify a different priority in each log
statement. Most syslogs however, mean that a given priority includes
all priorities that are higher as well, so this may not work exactly as
you think.
