[I'm just wading back into a mass of neglected email. Long story.] Chris is right, this is precisely why the interface is versioned, and there is at least one version of libcap that was written to support this versioning scheme cvs -z3 - -d:pserver:[EMAIL PROTECTED]:/cvsroot/linux-privs co -r libcap-pre2 libcap I'll try and unwind all the threads of email I've been neglecting and have something useful to say over the next few days.
