What about
Agnula? How do you upgrade
individual packages? How do you back out the upgrade if there's a
problem? Do you manage a separate "test" environment to keep from
bringing down your DAW?
I'm using Agnula on a double-booted system. I've got Woody/DeMuDi-1.0 on hda
and Sarge/DeMuDi-1.1.0 on hdb I've set up chroots in both directions so I can
access the one while booted into the other. It works for me.
You'd probably want to track the Agnua/unstable packages - they do maintain
ReHMuDi packages too, which I imagine you can install on top of Red Hat same
as Debian. You may even be able to use apt, I don't know.
At least on their last release they (ReHMuDi) were not using apt yet.
