For now, it's fairly easy to build a copy of the older version of dhclient to work around this, $ cd $HOME $ cvs -d anon...@anoncvs.openbsd.org:/cvs get -r OPENBSD_5_2 -d dhclient src/sbin/dhclient $ cd dhclient $ make $ sudo make install or you could try using a client from ports (e.g. isc-dhcp-client), hostname.em2 would look something like the below, though I don't know whether this will cope with rdomains correctly, rdomain 1 !/usr/local/sbin/dhclient em2 alias 192.168.100.2 255.255.255.0 There are potential problems when you upgrade; be prepared to change config to avoid the manual address setting so you can use the standard dhclient if you need it (this type of program is more likely than most to be affected by kernel/userland interface changes).
