1) Do not use beta/test software to test reliability of things.  The 
kernel had debugging information in it, was not optimal, the OS wasn't 
stable, etc, etc, etc...

2) Fedora Core 2 Anaconda DOES support xfs/jfs/reiserfs.  You have to 
pass these as options at boot time to the installer.  (linux xfs jfs 
reiserfs)

3) Fedora Core systems are build around ext3.  Usage of other file 
systems is not tested very well, and unexpected problems may occur.  
This is not due to a file system problem, more of an operating system 
not designed to use said file system.  To properly test, you should 
test an operating system that targets said file system for full 
operability.

4) NFS may not be an optimal test.  One would start with local disk 
access, then extend it to other scenarios which may bring their own 
instabilities into the picture.
