Can't agree more. We use stow to install certain pieces of software into
AFS, usually one-off and standalone scientific software (we're in
For everything else, we use the package manager. RPMs really are easy to
make. Perhaps even easier than installing the same app in AFS. Even if
there was something like rpm for afs, that would only make the two methods
(installing on local disk or installing in afs) equivalent (ignoring any
issues of permission). This also assumes you're running the same version
of the same OS everywhere (for example, we use @sys symlinks, but in our
environment amd64_linux26 isn't the same everywhere).
Follow the principal of least work: Is it more work to install an app into
AFS, or yum/apt-get/etc install.

That's what cfengine or puppet are for. IMO, any time you have to manage 2
or more machines, you really do need something like cfengine to do
complete configuration. If you can't blow away entire machines and have
them automatically reinstall and converge back to their previous state,
then you're really not managing your systems.
