Diskless machines, booting with pxeboot et.al.
under 5.2.1 and above.
>Description:
Right now during a diskless boot /conf/default, /conf/b-cast
and /conf/ip address is checked for system specific configs.
As some configs are very tied to HW, rather than to the subnet
the HW happens to be used with - it can be useful to tie certain
configs to the mac address.
The patch below add this facilities very much along the
lines of that supported by Solaris.
>How-To-Repeat:
Patch, reboot diskless machine.
>Fix:
