Hi.

With Guix at 47d0346553fdad9795c9390a60944ccaad7e5255, I'm unable to
build a package (see attached patch) requiring a recursive git-fetch to
get the sources:

$ ./pre-inst-env guix build bladerf
The following derivations will be built:
  /gnu/store/982zz7z94va89fxn79hpjil5wp0v49pn-bladerf-2023.02.drv
  /gnu/store/5rlqf4srlnnymsv93ydxkgxwgfszkszw-bladerf-2023.02-checkout.drv

Initialized empty Git repository in /gnu/store/fhlm9zxs4r4cgapbngckpzrs8rnzf1l2-bladerf-2023.02-checkout/.git/

 * tag               2023.02    -> FETCH_HEAD
Note: switching to 'FETCH_HEAD'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 41ef634 Revert "libbladeRF: update compatibility for FPGA v0.15.0 from libbladeRF 2.4.0 to 2.5.0"
