Starting with GHC 7.8.x, fingerprints are written into annotated & gpg-signed release tags:
http://git.haskell.org/ghc.git/tag/refs/tags/ghc-7.8.3-release
That way you're able to restore via the fingerprint for a given release via:
./utils/fingerprint/fingerprint.py restore -f <(git show ghc-7.8.3-release | grep -F '|')
I'm just surprised I couldn't find that described anywhere in the wiki, I was sure it was written down somewhere...
Oh, pretty useful. I also couldn't find it on the wiki and this page https://ghc.haskell.org/trac/ghc/wiki/GitRepoReorganization even claims it's going to be obsolete (starting with 7.10?). Google shows that something related was mentioned in https://ghc.haskell.org/trac/ghc/wiki/Building/GettingTheSources?version=93 but the new version of the page missed that info. This emails refers to the no-longer available info on the wiki, too: https://www.haskell.org/pipermail/ghc-devs/2014-January/003930.html I wonder what happened and which info is meaningful only for GHC < 7.8 or even ==7.8 and which parts make sense for 7.10 as well.
