While building the package of Guix itself [0], I noticed that Savannah
can't serve cheap "shallow clones" of the commits that these packages
are based on, so users will end up doing full clones (260M on
disk):

I'm reaching out to the Savannah admins to ask them about this, and if
it has any unduly negative affects on the Savannah infrastructure.

Maybe these commits should be tagged?

I poked around a bit and found that Savannah can serve shallow clones of
random commits, but does not allow shallow *fetching*, except for
special things such as Git tags. We fetch instead of clone.

Weird, what’s the difference between fetch and clone technically?  I
believe commit 329dabe13bf98b899b907b45565434c5140804f5 moved to “fetch”
precisely so we could do shallow clones.

I don't know. It's definitely weird.

I had researched this before and the option the git server is missing is
uploadpack.allowAnySHA1InWant [0].  Unfortunately last I check in
#savannah their machine (vcs0) is using an older Trisquel stuck with git
v2.11.0, one patch version before when the above feature was introduced
(v2.11.1)!  If I understood correctly, they have a new VM vcs2 but it
needs to be completely setup before they can switch.

Savannah is now using Git version 2.17.1. I wonder if we can have this
option enabled now? I checked and the problem described by this bug
still exists.

You'd want to check in #savannah, I think.  It'd help reduce bandwidth
and hasten 'guix pull' a bit if it were now possible, I think.

Thanks!
