You're probably on a system where /dev/shm is a symlink to /run/shm or something
like that.  Nix's chroot currently cannot handle that: mounting a new tmpfs on
/dev/shm fails because the symlink target (/run/shm) doesn't exist in the chroot.

See also http://lists.gnu.org/archive/html/guix-devel/2014-01/msg00144.html.
I'll try to come up with a fix for this.

The "none" is fine because it's a tmpfs.
