In addition to Nathan's encouraging words, XFS should be much less
volatile than a newly developed FS in this respect ... we are locked
into the IRIX XFS MIPS on-disk format, and that is the most likely
point of dependence between kernel version and user tools. This "lock"
in is for disk migration between IRIX and Linux, and for the clustered
CXFS product where both IRIX and Linux (and other assorted systems)
will have direct, concurrent access to the filesystem on disk, so there
is no room for making the on-disk formats different.
Also the IRIX XFS MIPS on-disk format is not going to change due to the
size of the installed base and our compatibility commitments to IRIX
customers.
And the Open Source format _is_ the IRIX MIPS format.
