I had success upgrading from RH7.3 to WBEL3, but I did have to manually
fix several glitches. Still much better than installing everything from
scratch. So I'd say if your UNIX/Linux skills are above average you will
probably not run into anything you can't overcome. If all you have are
newly minted RHCEs and MCSEs trying to learn, better make arrangements for
a good UNIXhead to be on call in case you get stuck. And of course a FULL
backup should go without saying. I migrated to a new machine at the same
time, which gave me the warm fuzzy feeling that if I couldn't get the new
box going before the deadline I could always just plug the network cable
back into the old one and punch the power button.
As for which rebuild, they all seem to be fairly similar. The differences
are subtle:
With WhiteBox I'm trying to stay as close as I can to RHEL3, but think
that having it self host is important also. I just think an Open Source
OS should be self hosting; what good is the source if it won't build?
One benefit of this is that if I disappear it shouldn't be hard for anyone
with a working WBEL installation to rebuild errata that will match.
Tao appears to have went to a lot more effort to make their rebuild an
exact copy, examining each package and trying to determine if it was built
on RH9 or RHEL and recreating that environment to rebuild that package in.
Pro: more exact clone. Con: harder to build your own packages should the
need arise.
Centos is a side project at the cAos project, I get the impression it is
something to ship while they get the cAos distribution up to "enterprise"
quality. Haven't dug too deep into their build philosophy.
