[rescue] DNS on SunOS 4.1.4

[silcreval]

Todd - thanks for that - I'll give the mods a go.

Dave - would be great if you could share that.

One thing I struggled a bit with was getting an NFS share to work. I generally use a Raspberry Pi as a file server - mainly because it costs just about nothing to keep powered on - and have various shares on there including AppleTalk, Samba and NFS. 

I tried getting NFS 2 support running on the RPi but none of the config options worked. I'm guessing it would need some kernel magic to get enabled.

In the end I shared a clone of the drive from another Sun box running Solaris 7, and all worked fine. I'll figure out how to get the RPi to support NFS 2 one of these days...
