The Fedora Project moves in with EPEL, Extra Packages for Enterprise
Linux, perfectly suitable for a CentOS machine and with the same release
and 'support' cycle.
Not entirely sure what you mean here. I think what was being called
for was a release whereby it's "supported" (with security updates,
etc) beyond the current 1 year, however perhaps not as much as the 7
years that RHEL is supported.
However, as Matthew said in the e-mail that came in as I was writing
this, there was little interest in Fedora Legacy when it existed.
What makes us think that there's more of a demand now? It's either
the short, bleeding edge release cycle of Fedora as we know it, or the
long release cycle of RHEL. Both serve different purposes.
