~ruther/guix-local: file-systems: Allow for bind-mounts of named sockets.

bb5cad4eb2473889dd9938ab3d0453d30b0765e7 — Ludovic Courtès 9 years ago 6ddf4fc

file-systems: Allow for bind-mounts of named sockets.

Previously a named socket such as /dev/log would fail
the 'regular-file?' test and we'd end up mkdir'ing it.

* gnu/build/file-systems.scm (regular-file?): Remove.
(mount-file-system): Change (regular-file? source)
to (not (file-is-directory? source)).
