What I can find is a lot of pages written from 2003 to about 2012. The few that
are newer (newest 2015 which is still ancient by 'modern' standards -
- - I think
I was running debian 8 at that time) are talking about windows + a
couple different
distros. It seems that what I'm doing is something quite different. So
there just isn't
any information that I can find (looking through about 100 pages of
'supposed' links).
Any pointers as to where to look?
