Straight from the info page for "chmod->File Permissions":
------------------------------------------------------------------------
[snip]
In addition to the three sets of three permissions listed above, a
file's permissions have three special components, which affect only
executable files (programs) and, on some systems, directories:
[snip]
2. set the process's effective group ID to that of the file upon
execution (called the "setgid bit"). For directories on some
systems, put files created in the directory into the same group as
the directory, no matter what group the user who creates them is
in.
[snip]
------------------------------------------------------------------------
Therefore, the setgid bit on a directory will try to force any files
created in that directory to be owned by the same group that owns the
directory, if the OS/C library supports it.
So, yeah, you're totally wrong, at least in the case of the setgid bit
on directories. :)
