(For now) fedora-specific rc.linux file to initialize the swap partition
ala freebsd7/rc.freebsd. We need this currently for the new remote nodes where we have to load partition images and not a whole disk image (because we download a copy of the image to the hard drive and we cannot have that mounted and reload the entire disk). Anyway, with a single partition image the swap partition will not be "loaded", aka initialized, and we are left without swap. Now the rc.linux script takes care of that on first boot.
