I've noticed that (as of 2.6.25, at least) the kernel doesn't autostart
arrays with V1 metadata.  In autostart_arrays(), md_import_device() is
called for 0.90 arrays only, and there's currently no sort of
autodetection of the superblock position for V1 metadata.

Is this simply a matter of the code being unwritten, or are there other
reasons that V1 arrays aren't autostarted (such as the SB format being
unfinished)?  My only real motivation to use V1 metadata is the unhashed
homehost field, which I'll give up if the SB format hasn't stabilized yet.

Thanks,
