Version bumped to represent the major change from previously
(as was done for stage2)

Because dracut uses udev and because udev has likely already started
the interface, we will see things out of order.

Large sections of the probing code could probably be removed
but for the time being we should probably consider removing
this error message completely

Now that dracut runs stage1 earlier, we need to store it's exit code
for later reuse. In this, the separate dracut module will just write a
flag file in /run/drakx/ to indicate that we want to re-exec /sbin/init
(after doing some symlinks and /usr bind mount) rather than run the install.

As a result there is no need to return 0x35 ('procced') so just return
0 and keep 0x35 return code for when we really do need to restart stage1
(e.g. on a fatal error). The dracut module should loop if 0x35 is
ever returned.

init is now solely responsibe for running stage2 (be it install or rescue)
as stage1 is now run earlier by dracut.
