Remove tabs
initrd: Add ehci_pci and hid_generic

tests/misc.nix: Test nixos-rebuild --help
Return exit code 127 if a command is not found
Add varnish to module-list.nix
Merge pull request #125 from MarcWeber/submit/when-enabling-wacom-add-xsetwacom-to-path

filesystems: add priority option for swap devices.

Useful for setting up raid0-like load balancing for swap.
By giving multiple swap devices the same prio.
