No. fork files/resource forks (or whatever you choose to call them) have been discussed multiple times. If I recall correctly, one showstopper was fixing the archive tools. There was also the generic argument that Linux doesn't support them. Then there was the issue of what VFS/VOP changes were required. (The FreeBSD VFS carries vnode locks across VOP calls and is at what I would call a lower level than Solaris.) --> Which all comes down to who will do the work? If I recall correctly, there was a time when a group associated with CERN needed them to transition away from Solaris. Anyhow, maybe the discussion will happen again here and now, rick > > Ced > -- > Cedric Blancher <cedric.blancher@gmail.com> > [https://plus.google.com/u/0/+CedricBlancher/] > Institute Pasteur >
