  distro release and reproduceability  i started a thread on
centos-devel: but actually it's nothing to do with centos rather
rhel and fedora. the question comes when i try to rebuild centos
on itself. it turns out not possible what's more it's almost
impossible to rebuild (or takes much more longer then the build
time). the problem is the process how each packages and updates
added to the distro ie. just the new packages rebuild and
doesn't care whether the old packages still build. and easy
example the latest mass rebuild. there were some problems with
since new gcc can't compile old 'buggy' code, but there are many
problems which has nothing to do with gcc, rpm or i586. the
first question: - is it a goal for fedora to be able to rebuild
itself? i hope the answer is yes:-) - how we can achieve this
goal? imho the current policy and process is not good enough.
first of all it'd be useful to somehow automatically check all
spec file during builds (eg. don't put check into %build, don't
put build into %instal
