Hey Ludo,

I think that's reasonable too. I tested it locally and have the
following command:

--8<---------------cut here---------------start------------->8---
strace -c -e stat,openat ./pre-inst-env guix
--8<---------------cut here---------------end--------------->8---

drop from 1671 calls to 1017 calls, which is nice.

The patchset looks good to me.

Thanks,

Mathieu
