This is somewhat off-topic because I'm asking due to what I've noticed
on my desktop Linux. But why are some things "setgid"? Is it just so
that some files and/or subdirectories can be written to? I ask because
I've noticed that most of the games on my desktop have the setgid
bit on
and have a group of "games". Anybody know why? What does the game do
that needs a "setgid"?
Perhaps if I understood this about games, I would understand the
general
reason to use setgid. At least, that's my story, and I'm sticking with
it!
It is indeed generally to allow write access to a particular file or
directory.
Games, for instance, usually use the bit to update a shared
scoreboard writeable by the games group.
