Trying to an old mac to good use, I'd like to install NetBSD/mac68k on it.
However, the mac68k installer, and boot app can't seem to make use of the
IDE supported in the current kernel I'm using (ugh, I hope they fix this
SCSI-centric stuff soon :P)
Anyway, right now I boot the kernel, it can't find a root file system,
asks me for one. I specify ae0, then for dump device, I don't know what to
put there, so I don't :-). Then I'm asked for file system, and I type in
nfs. It uses bootp, contacts my bootp server, then dies with the
following: 
nfs_boot: getfh - no pathname
cannot mout root, error = 5
My bootptab file has the following:
.default:\
        :sm=255.255.255.0:\
        :ds=192.168.0.1:\
        :ht=ethernet:\
        :sa=192.168.0.0:\
        :gw=192.168.0.2:\
        :bf=null:
hercules:td=/export/hercules:tc=.default:ha=00401056d39d:ip=192.168.0.20:

I have the entire file system in /export/hercules...here's my exports
list:
/exports/hercules 192.168.0.20(rw,no_root_squash)
/exports/hercules/swap 192.168.0.20(rw,no_root_squash)B
What Stupid User error am I making here? Thank you very much for your
help.
