And know that it is much appreciated.  But your proposed solution will
only work for some machines, and slow down a lot of others.  I wish
there was a way to figure out if some disk are going to show up soon,
but as far as I know, there is none.  Perhaps a better way is to check
if the root device is available, and if not, wait a bit.  This way,
the boot will be more robust while still being quick in the common
case.

Something like

  while [ ! -f $rootdev ] ; do
    echo "missing root dev $rootdev"
    sleep1
  done

in front of the fsck call.  There should be a timeout or loop
counter to make sure it do not wait forever.

Or, perhaps the boot should be event based and fsck only called when
the event from the kernel for the given device arrive.  Then we get
another issue, which is to wait for the root file system to be mounted
before continuing.

Happy hacking,
