Thread-topic: [Xen-users] Upgrade Proceedure
The question is if doing an upgrade do you actually have to uninstall
the files? I mean if its an upgrade then wouldn't just untaring the dist
directory and running the install thing work?

Not at all. It just takes the files in the "dist" directory (which is a
copy of what's been produced in the individual build directories, e.g.
xen.gz, qemu-dm, vmlinuz, kernel modules, hvmloader, etc, etc), and
copies it out to wherever it goes. Have a look at "dist/install.sh".
It's not complicated, it essentially just copies the files from
"dist/install" to whatever destination you specify (defualt is "/").

Great if you have the environment to build the RPM, but if you take the
xen-unstable.hg repo, it doesn't come with spec-files to make RPM's

Obviously, most distributions will use some sort of packagemanagement,
and that solves most of those problems.
