Ehm, as far as I understand, this will not help me repair a disk as
xfs_repair -n does not repair anything - or does it?

correct, you can only repair a fully unmounted filesystem with
xfs_repair, that means you cannot repair the root filesystem unless
you boot from an alternate root.

Yes, this has been annoying.  Enough so that I made this little
script that would provide me with another root to boot from.

see http://www.sinz.org/linux for details on this tool.

(It has a number of requirments that are based on my needed environment
but it has worked across a wide range of systems.  The main thing is
that the recovery kernel have devfs and procfs)
