The above rule does not seem to work.

When I try to debug it, udevadm fails to see the new 90-automount rule:

	> udevadm test {udevadm info -q path -n /dev/sda1}
	calling: test
	version 3.2.4
	This program is for debugging only, it does not run any program
	specified by a RUN key. It may show incorrect results, because
	some values may be different, or not available at a simulation run.

I guess Guix passes some "path" parameters to udev which are missing
above.  The proper path for the rules on my system is:
