Hello,
It looks like my darcs-fu is a bit rusty. I've attached the patch with all of the changes to this message for adding the missing functions to unix package
It was a while ago that I looked into uid/gid issues on Unix, but as I remember it it wasn't very straight forward, especially for setting. Particularly worrying was that it is fairly easy to get into the position where one thinks that the uid/gid has been irreversibly changed from root, while in fact this isn't the case. I also remember that the "correct" way of changing uid/gid differed between Unix platforms. A quick look at this patch leads me to believe that this hasn't been taken into account. Am I correct in this? The paper that removed the mist surround uid/gid was Setuid Demystified[1]. /M [1]: http://www.cs.berkeley.edu/~daw/papers/setuid-usenix02.pdf -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus identi.ca|twitter: magthe
