#719 switcher can select tags for uninstalled packages
If nothing was entered in the switcher configurator
menu switcher currently selects the first tag available in
the database, even if the tag belongs to a package
which was NOT selected to be installed.
A reasonable default setup is to select mpi=none as
system wide setting if nothing was selected in the
configurator menu. This way users aren't forced to use
an unwanted MPI version and many sysadmin trouble
can be avoided.

I disagree. An MPI should be selected by default. This is an HPC OSCAR
cluster, after all -- MPI is a common thing that people do on them. The point
of OSCAR is that it should "just work" -- including MPI.
However, the code could/should be made smarter to ensure that only an
MPI that is installed is selected.

OK, I see your point. So let's fix the default setting to
avoid uninstalled packages.
To explain my pain: we're frequently using 4-8 MPI
versions because of different ISV applications and
compilers. Having no path to an mpirun is often much
better than using the wrong one which comes from some
system setting one doesn't know about. But the solution is
simple, one _can_ select mpi=none in the configuration
step...

Agreed.
Now I understand the example with 6.5.6 in the other bug (if you have ISV
software compiled for a specific MPI). Sorry about marking it as open -- I
clicked on the reply link as soon as your first mail came in, and it therefore
didn't have your "fixed" flags set on it when I submitted.

Changed subject of bug.
Fixed in trunk (r3682).
Adapted packages/switcher/scripts/package_config.pm to
allow only the tags from selected packages. Simplified ODA
access code.

Erich, can this bug be closed?
