xfs_repair of root filesystem

[Jeremy Jackson <jerj@xxxxxxxxxxxx>]

Hi,

I'm wonder what's the official word about xfs_repair on a read-only
mounted fs.  The utilities complain for me, so I have to boot from a
repair partition to fix XFS (a while back when the shutdown files in use
bug was still a problem).  Ext2 has no problem with this.  I'd just to
know for future reference, so I know if I have to have a spare root fs 
or not.
