right, that is a good point. I've switched the snapshot version to Git
instead (and cleaned the expression up a bit in general). Let me know if
there's still trouble!

By the way, does anyone know the purpose of the SANE module in NixOS? I
guess it's supposed to make some udev rules available to the system, but
that does that actually work? I noticed, for example, that the udev
rules refer to a group name which won't even exist on NixOS.

Take care,
Peter
