[mythtv-users] Problems with system-config-netboot Creating Diskless Myth Frontend

[Craig Courtney]

I would highly recommend looking at minimyth (http://linpvr.org) instead.  I
tried doing netboot script in redhat and got everything configured through
those scripts and tutorials.  Once you get that environment setup you still
have to compile your own kernel to get nfs root mounting to work... which
causes pain in using pre-packaged rpms.  It's just a major hassle and a pain
to keep up to date afterwards.

It took me about 45 mins to get a fully functional diskless front end setup
with minimyth, and about another 20 to convert my other 2 front ends to
diskless.  It takes about 1 minute after download time to update a minimyth
install to the latest as well.  The only real downside is minimyth is not
really secured at all, but no network boot really is.
