[olug] disable the default search domain?

[David Walker]

I recently had to fix this in my network.

In resolv.conf I specified a domain that doesn't exist as you see
below.  In my case nothing was negatively affected.  This is the same
basic idea as what you were doing.

nameserver 76.85.228.100
nameserver 76.85.228.101
domain vorteon.pri
