IMHO this looks more and more like the udev rules has to be split into
at least two categories:
- a basic set that is used during boot and early system setup. Services
in rcS.d are allowed to rely on these rules only, and these rules must
not rely on anything outside the root file system.
- an extended set that is activated at the beginning of rc[2345].d and
contains all the bells and whistles GNOME & co. wants.
The separation can be done by depending on an environment variable that
only gets set using udevadm when transitioning to the default initlevel.
Or even better, let's export the current initlevel as an env. variable
in udevd, and let rules in the extended set test for that.
