[opam-devel] Fedora RPMs

[Gabriel Scherer]

opam-devel, is there a recommended fool-proof way to save an opam root
before installing another OPAM version to experiment with it, and be able
to come back to one's usual environment?

I'd like to test Jon's packages, but I'm a bit wary of losing/corrupting
the dozen of switches I have already. I'm thinking of basically
  mv ~/.opam ~/.opam.bak
  <uninstall my opam>
  <try the packages then uninstall them>
  mv ~/.opam.bak ~/.opam
  <reinstall my opam>

If there is nothing wrong with this approach, it might be useful to
document it somewhere -- it's not in the developer manual for example. This
could be useful when asking users to test beta-releases of OPAM as well (I
know I was unhappy when I tested 1.2 and my repository format was silently
updated to 1.2, making it harder to go back).
