Hi Jakob :)
Your solution of exec'ing ourselves MUST undoubtly work (well, I know that this an affirmation that I will lament XDDDD), because it only relies on 'exec()' passing the argv[0] you provide as the argv[0] of the invoked binary, and that should work or programs like '/bin/login' will stop working... They rely on the same principle, since they need to prepend an '-' to the shell name to make it a login shell :))) Didn't remember this until now!
So, if you do 'execl(ourselves, "my new name", ..., NULL)', the argv[0] received by the binary specified in 'ourselves' MUST be 'my new name'. Otherwise '/bin/login' and a good bunch of shells won't work...
If you happen to come to Spain at any point in the future, just tell me, I'll buy you a beer (or crack, or whatever you use XDDD).
Thanks :)
