That said, to do such a port there is the need for a Mac OS X developer... since Mac OS X is still Unix that should not be too hard, but I don't know. For instance, does ptrace() exists (check via "man ptrace")? I think that incapsulating this call is not a work in progress, and it won't be until we don't have at least another API to port UML to. Also, I heard rumors of a FreeBSD port (although I don't remember if it was just a request); since the FreeBSD roots of MacOSX, a lot of code could probably be shared by those ports. -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- This SF.Net email is sponsored by: New Crystal Reports XI.
