It works either way.   If you want to match the client ID, declare the
host as follows:

host foo
  option dhcp-client-identifier 1:8:0:2b:4c:29:5d  
  fixed-address confusia-3.fugue.com;

This assumes that the client identifier is an ethernet address
declared according to the latest draft on DHCP options.   Older
versions of FTP software's DHCP client use fairly long ASCII text
client identifiers.   Unfortunately, these must also be entered as
binary data.

I should say that as far as I know, nobody's tried this code, so it's
possible that it's buggy.   If you run into trouble, let me know and
I'll try to resolve it as quickly as possible.

BTW, There will be a new release of ISC dhcpd today to correct some
bugs in the Beta 3 release.
