Hello,

The "jfs-root-os" test is failing since a few weeks. See:
https://ci.guix.gnu.org/build/3038686/details.

The issue is that some "link" syscall fails during "guix system init"
call.

Mathieu

This is fixed by 8b221b64a552d31e241701aa5c6d339287a7a15b on master. The
problem was occuring inside "deduplicate" procedure of (guix store
deduplication).

This procedure uses scandir* to check if the path to deduplicate is a
directory. The problem is that JFS does not support d_type so, the file
property returned was 'unknown. As this particular case was not handled,
directories were not detected as such, causing the procedure to call
"link" on a directory, which was failing.
