This is an important issue that should be handled in the future, say 7.1
or 7.2.

I think Red Hat Linux definitely needs some tools to upgrade a live
system.  The main reason for this is that you can do it remotely.  I can't
see anything more annoying than having to walk through every Linux
workstation / server and perform the upgrade w/ CD-ROM or bootdisk,
when I just as well could do it via SSH (in the future? :).

Compare this with the upgradeibility of e.g. FreeBSD (cvsup, make world),
and Linux has still ways to go. :-/

Actually, in Pinstripe, you _could_ do 'anaconda --method upgrade', but
it'll die:

you're running me on a live system! that's incredibly stupid.

Tools like AutoRPM aren't enough, because there will always be some
dependencies missing, pretty interesting packages added, problems with
packages that may need heavy scripting/tweaking (like kernel)  etc.

Combined with a tool to handle all those .rpm{save,orig} files (merging
the configurations where needed), we'd be in heaven :)
