Please note even Fedora is also unspported
What does support mean anyway? Hasn't anyone heard of Debian? No one ever needed support and it's been doing great ever since it started.
The community ... i.e. GLUGs are equivalent to support... right? Google = support HOWTO docs and MAN pages = support
And if you really want to pay for support... there are host of vendors for the GNU/Linux platform that a just waiting to do so irrespective of which flavor you are using... and that's the least of the problems according to me...
