I'd like to raise the question why do we need the full SHA1 for as the
build ID?

Using the abbreviated version looks weird enough for users, and I think
the full version won't add anything.
Technically they are the same (correct me if I'm wrong).


The abbreviated form is much more prone for collision than the
unabbreviated one, and the core git repo indeed already has at least one
collision of abbreviated SHA1s.  Try "git show 349fa28a".


Thanks, although I couldn't find the other commit (the first is
349fa28a5998d10b110da1a7fcc6b5b24d5940b1)
