Sounds plausible!

The code in (guix git) determines expiration based on the mtime of
sub-directories in ~/.cache/guix/checkouts.  But that’s bogus, no?

Yes, and the Internet confirms: a directory’s mtime is only changed when
a file inside it is renamed, added, or deleted.)  Oops!  So it would
depend on how frequently you pull, and perhaps on the file system you
use, go figure.

The patch below should fix it.  Will push shortly, thank you!
