I did. The point is, as I understand, how to make the gluestik work with the non-global cookie jar, right? You proposed the Ssystem() expansion, but this would make the entire modification pointless (the point of making jar private is avoid a situation when a buggy or maliciously written program destroys the jar thus influencing all processes which would look it up; with Ssystem() modifying all the copies this would still be possible). If gluestik would be an XDD, it would be able to place its cookie into kernels cookie jar. This way the STiK cookie would become available for all processes, and no kludges in Ssystem() are needed ("wolf/ox" solution). > > Obviously, if someone doesn't need such safety, can give up the private > > cookie jar and use STiK programs ad libitum. > > It's just the problem that exactly these users are not abale to compile a > kernel by itself. It is up to you to decide, what compile switches to choose for the distribution kernel. Besides, this is just an experiment. If it turns over, that it creates more problems than advantages, restoring the previous situation is harmless.
