... and would make QA impossible. Red Hat does its QA on the binary
packages that they provide and if they are happy with the result it
doesn't matter if the package was rebuilt the day before or came out
of a Fedora build one year ago. The whole idea of using well known
binaries (and which go through QA and can be supported) is what keeps
people paying to Red Hat. It's also what keeps many people downloading
CentOS packages and not rebuilding the SRPMs themselves. If there's a
problem they can compare with others running _the same binaries_ and
find out if the problem comes from the binary or not; with binary
packages built in a random order and random build environment, there
is no possibility to talk about reproducible behaviour and makes any
comparison meaningless.
So how do you (the OP) propose to do QA and bug tracking when each
single package update can trigger an avalanche of other updates ?
Please note that I also find good the idea of self-hosting. It's a
very good feeling to take the SRPM and have a binary package after
just a 'rpmbuild -ba'. But I think that this goal has to be balanced
with other goals to make a distribution.
