79-GiB opam checkout in ~/.cache/guix

Auntie Guix,

My SSD hurts & my ~/.cache/guix feels funny:

  ~ λ du -hs ~/.cache/guix/checkouts/* | sort -h
  560K	/home/nckx/.cache/guix/checkouts/hp4…
  1.3M	/home/nckx/.cache/guix/checkouts/l74…
  2.5M	/home/nckx/.cache/guix/checkouts/hep…
  219M	/home/nckx/.cache/guix/checkouts/pjm…
  79G	/home/nckx/.cache/guix/checkouts/f5u…

…wait, what the hell is that last one?

  ~ λ cat ~/.cache/guix/checkouts/f5u…/.git/config
  [core]
	bare = false
	repositoryformatversion = 0
	filemode = true
	logallrefupdates = true
  [remote "origin"]
	url = https://github.com/ocaml/opam-repository
	fetch = +refs/heads/*:refs/remotes/origin/*

I have no idea what this means or what has happened.  I don't 
remember running an opam importer recently, although I've probably 
run ‘guix refresh’ on an opam package or so.

Still.

According to GitHub, the repository is only 70.9 *MiB* and when I 
clone it locally it's still nowhere near a gigabyte:

  ~ λ git clone  https://github.com/ocaml/opam-repository
  Cloning into 'opam-repository'...
  Receiving objects: 100% (316368/316368), 69.07 MiB | 5.70 MiB/s, 
  done.

  ~ λ du -hs opam-repository/
  562M	opam-repository/

Halp,

T G-R

Did you possibly get recursion into a lot of unintended submodules?

What would you get if you cd into opam-repository above and did
per "man got-clone" below (cf. "This is equivalent to running ..."

    git submodule update --init --recursive

(i.e. with no <pathspec>, to get all submodules)

What is du -hs ../opam-repository after that finishes?


copied from man git-clone:
--8<---------------cut here---------------start------------->8---
	--recurse-submodules[=<pathspec]
	    After the clone is created, initialize and clone
	    submodules within based on the provided pathspec. If no
	    pathspec is provided, all submodules are initialized and
	    cloned. This option can be given multiple times for
	    pathspecs consisting of multiple entries. The resulting
	    clone has submodule.active set to the provided pathspec,
	    or "." (meaning all submodules) if no pathspec is
	    provided.

	    Submodules are initialized and cloned using their
	    default settings. This is equivalent to running git
	    submodule update --init --recursive <pathspec>
	    immediately after the clone is finished. This option is
	    ignored if the cloned repository does not have a
	    worktree/checkout (i.e. if any of --no-checkout/-n,
	    --bare, or --mirror is given)
--8<---------------cut here---------------end--------------->8---
