Re: it's safe to run a web hosting server with the unstable distributions ?

One of the most interesting things that actually got me charmed with
debian was a copy of debian 0.99beta that I had on some old cds. I
remember that day well. There were some problems and some functionality
missing but overall it's useful. I could install almost everything in the
distribution on my entire small partition and it worked great.

If you need source that badly or ever need it in the future just get some
copies of everything and burn some CDs for permanent archival storage. You
can't go wrong there.

I think in upgrading something like perl4 you could hire say one
programmer to do a temporary job and be on call for you. Then fix
everything. I may be incorrect but isn't most of the core language of perl
pretty much constant? Kind of like C/C++ or perl/delphi
