Pass number 1 in magic in that it is sequential.  Traditional
wisdom (or lack thereoff) have only put rootfs in pass 1.

Until my patch, pass 1 would certainly be better for ccd
than pass > 1.

I've always assigned a ccd (this would apply to Vinum volumes as well,
I'd think) a pass number of 1.  According to the fsck manual page,
each filesystem with a pass number of 1 is processed by itself.  The
code might say something different (which I've looked at but can't
quite figure out how that is handled).  If assigning a pass number of
1 doesn't do that, we probably should either fix the code so it does,
or change the manual pages to match.  :-)
