See the above conversation... 8sync now uses `git-file?' in its guix.scm, a predicate check which allows for checking out the whole local directory as a "source" for testing a package. I borrowed it from Dave who originally adapted it from some code in Guix itself. See: http://git.savannah.gnu.org/cgit/8sync.git/tree/guix.scm#n62 This is pretty handy; probably other projects would like to make use of it. What do we think of making it a generally available utility? - Chris
