>Description:
The dhcp client in /usr/src/contrib/isc-dhcp does not support setting
hostnames. Also, it currently sets the hostname to a hexadecimal
representation of the hostname instead of the actual text. (Sigh.)
>How-To-Repeat:
Well, you need a dhcp server setup that sends hostnames, and a client
that requests hostnames. Then, boot the system. The hostname will not
be set. Then, apply the first patch to /usr/src/contrib/isc-dhcp/clients/scripts/freebsd
and the hostname will be set to a long, annoying, hex string. Finally,
apply the second patch to /usr/src/contrib/isc-dhcp/common/tables.c
and the hostname will be set properly.
