  Modified files:
    sys/conf             options 
    sys/dev/vinum        vinum.c vinumhdr.h vinumio.c 
  Log:
  Finally make vinum ready for the root filesystem in FreeBSD 5.x.  (A
  similar patch has been in 4.x for a while, but is more hacky there.)
  
  For this to work, vinum has to be loaded early (e. g. from
  boot/loader), for obvious reasons.  If the kernel env variable
  (aka. loader variable) "vinum.autostart" is set, vinum then asks the
  sysctl kern.disks for all available disks in the system, and scans
  them for possible vinum headers.
  
  For statically compiled kernels, this behaviour can be obtained even
  without boot/loader by using "options VINUM_AUTOSTART" (though this is
  not the recommended way).
  
  Alternatively, the 4.x way to specify "vinum.drives" is also supported.
  
  No further hacks (like the 4.x "vinum.root" variable) are needed,
  since in 5.x, mountroot() asks back at the drivers to have them
  resolve the name of the root FS into a dev_t (using the dev_clone
  eventhandler).
  
  (The MFC reminder below is for a partial MFC for vinum.autostart, the
  rest is already there in 4.x.)
