I've been wondering if this is really the authoritatively correct way to
do this. I know this is how the loader does it, for example, but I
recently stumbled over code in the X server that has some additional
checks and uses extra functions, including optionally a function called
issetugid(), in hw/xfree86/common/xf86Init.c.
Any idea about an authoritative source on this? I don't want to
cargo-cult something overly complex, but at the same time, the above
really does check less (e.g., it doesn't look at gids).
Cheers,
Nicolai
