Just jumping in to this thread, I've helped two people in IRC run 'guix pull'
with a working git tarball I found. Perhaps some code should be added to pull
the latest build that's been built on Hydra?

In the end it'd still be great to have rollbacks, the ability to specify a git
commit, ping Hydra to see which commits have substitutes that I could upgrade
to, and allow rolling back as if it's a package in my profile.

It sounds like a lot, but I figure at least one of those ideas would ease
things for people.

Jookia.
