Is Lustre GPL?  It was GPL as of version 1.0.4, but I was
under the impression that the newer source is not GPL.  CFS
has stated that they will eventually release the current
release (1.2) but they have not done this yet.  Version 1.4 
was supposed to be done in August, but hasn't been released yet.
Maybe version 1.2 will be released under the GPL when it is
no longer the latest release.
