I understand what you're saying, but I don't think the behavior agrees
with your statements. I've tried this on a couple different machines,
and the behavior is identical. No matter what I do, if a file is created
with the "None" group, the group file permissions are always identical
to the owner file permissions. I've tried playing with my umask and with
directory sticky bits. It doesn't matter. In the example above, my
parent directory is rather oddly, Chris.Users 000. The current directory
is Chris.None 775.
$ ls -ld . ..
drwxrwxr-x+ 1 Chris None 0 May 5 10:05 ./
d---------+ 1 Chris Users 0 May 5 09:35 ../
And again, changing the permissions of the directory doesn't accomplish
anything:
$ chmod 755 .
$ ls -ld . ..
drwxrwxr-x+ 1 Chris None 0 May 5 10:08 ./
d---------+ 1 Chris Users 0 May 5 10:08 ../
Changing the group for the directory doesn't help either:
$ chgrp Users .
$ touch bar
$ ls -l bar
-rw-rw-r-- 1 Chris None 0 May 5 10:10 bar
$ chmod 600 bar
$ ls -l bar
-rw-rw---- 1 Chris None 0 May 5 10:10 bar
$ ls -ld . ..
drwxrwxr-x+ 1 Chris Users 0 May 5 10:10 ./
d---------+ 1 Chris Users 0 May 5 10:08 ../
Taking the example one step farther:
$ chmod 600 bar
$ ls -l bar
-rw-rw---- 1 Chris None 0 May 5 10:10 bar
$ chmod 400 bar
$ ls -l bar
-r--r----- 1 Chris None 0 May 5 10:10 bar
And changing the group from "None" to anything else always fixes the
permission issues. chmod and umask suddenly start working as expected.
