Well, no, it's exactly because it _is_ modular that you can't just switch it out. If you want to be able to just switch things out they have to be free-standing. anaconda uses various other bits of the distro, because then we don't have to write things twice. But as a consequence, you can't just throw in an old anaconda build and expect it to work at all.
I prefer to think of it more as 'there's something wrong with every possible release cycle' - which is why this debate always goes around in circles and never gets anywhere. There are several things 'wrong' with the current Fedora cycle, but then there are several things 'wrong' with any conceivable replacement as well.
Colin Walters has been working on something similar called OSTree. IIRC he used some ideas from chakra along with a number of other systems that do similar things.
I know he's got it working to some extent (that is he has the multiple roots that allow for rollback) but i dont recall where he is with regards to the overall features he is wants.
tancracker I ment to write "your average newbie user is not using fedora... he is using mint/ubuntu"
a fedora LTS release would only make sense if fedora was more widely adopted and more newbie friendly.
enterprise and professional users will go for rhel centos debian, whatevers...
And I suppose the hardcore will go for arch gentoo whatevers...
that's what so interesting about fedora, it is clearly the superior linux distro but it doesn't quite know that
