Not really. I've made a few fixes in cvs since then, but never got around to creating a new release.

I'm not a lawyer, but I would assume as long as you didn't copy code from jfsutils, you should be able to do that. > I would also build basic support for JFS (mkfs.jsf and fsck.jfs) in > the toybox (http://www.landley.net/toybox/).

I haven't worked on BSD projects, so I'm no expert, but I believe putting GPL code into a BSD product is not feasible. > Is it possible to publish jfsutils on a more liberal license (MIT, > BSD)? Currently, JFS can not compete with XFS, and without good > support for this filesystem JFS will become increasingly marginalized. A similar request was made several years ago and IBM decided against it then. Since IBM released the code under GPLv2, they'd be the only ones that could release it under a different license, and I no longer work for them. I don't think they care much about JFS on Linux anymore, but it's still their enterprise filesystem on AIX, so I assume they somewhat care about the intellectual property rights. > > Best regards, > Daniel > ------------------------------------------------------------------------------ _______________________________________________ Jfs-discussion mailing list Jfs-discussion@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/jfs-discussion
