[ale] Simple group workarea

[James W. Lynch]

I don't know if you can do this the way you want, but if you turn on the
set-group-ID bit on the directory, then files created by anyone in
that directory will have the group set to the same group as the directory.

Did that make sense?

See:

<chinaberry 107> touch it
<chinaberry 109> ls -lat
total 2
drwxrwx---   2 root     root        1024 Nov 21 14:15 .
-rw-------   1 jwl      jwl             0 Nov 21 14:15 it
drwxrwxrwt   4 root     root         1024 Nov 21 14:12 ..

su
bash# chmod g+s .
exit

<chinaberry 109> ls -lat
total 2
drwxrwx---   2 root     games        1024 Nov 21 14:15 .
-rw-------   1 jwl      jwl             0 Nov 21 14:15 it
drwxrwxrwt   4 root     root         1024 Nov 21 14:12 ..



<chinaberry 110> touch xx
<chinaberry 113> ls -la
total 2
drwxrws---   2 root     games        1024 Nov 21 14:15 .
drwxrwxrwt   4 root     root         1024 Nov 21 14:12 ..
-rw-------   1 jwl      jwl             0 Nov 21 14:15 it
-rw-------   1 jwl      games           0 Nov 21 14:15 xx

See where after I did the chmod g+s the touch of xx generated a group 
ownership of games for the file xx.

Jim.
