A new category is fine … although my scripts also do not care much and
I have them do a search anyway. One could debate if topical categories
are really that helpful (a scheme as suggested by Kamil would enable me
to guess a package location rather reliably … if we dropped uppercase
letters from names). I hope any moving of existing packages is done
rarely. This breaks local patches, for example … creates work just for
work's sake.

I'm not sure if most clusters really run CentOS specifically, but I am
part of that trend (minimal software costs, maximum hardware delivered,
still somewhat supported by vendors → CentOS). I introduced pkgsrc for
the reasons you mentioned, combining it with differing toolchains
(local patch pending for using external MPI) to present a menu of
userspaces to the users. We want updated software, but also the
unchanged software we used 3 years ago to reproduce computations.
Versioned Pkgsrc prefixes give us that.

HPC is always a niche in terms of user count, but the traces in pkgsrc
are obvious (the whole geography category, for example … and even
things like wip/trinity).

Alrighty then,
