You have a very valid point here.
FreeBSD's support for other FS' is horiffic. Very little else is supported 
which I find very sad.
There is not even support for Solaris UFS. Something that would be really 
nice would be support for XFS.
I personally think that XFS is a really good FS with nice features.
