[I may not have this 101% exactly worded properly, but I am 99.99% sure
I have the concept correct.]
The examples you just gave are appropriate for what they are
specifically because they are in your own $HOME. Notice that in your
example, both user and group are user1. That is appropriate for $HOME,
but it is *NOT* appropriate for a wider-access data area in which all
images are often edited by multiple staff members.
More appropriate to this discussion would be /somedir/images
directories, containing myimage.tif
drwsrws--- 1 user1 mygroup 4096 Mar 25 11:28 somedir
containing
drwsrws--- 1 user1 mygroup 4096 Mar 25 11:28 images
containing
-rw-rw---- 1 user1 mygroup 35123 Mar 25 11:28 myimage.tif
On *nix Create-file perms should be set by the creating program based on
umask / directory perms.
If the perms of the directory /somedir/images look like drwsrws---
user me
group mygroup
then if files are created BY A MEMBER of the group "mygroup",
files created in /somedir/images should look like rw-rw----
(actually on my system they end up rw-rw-r-- for some reason).
I am speaking simply of file creation, for example, by doing
touch junk.txt
However, Gimp 2.6.6 on Ubuntu 2.04 refuses to create files using the
same methods that "every" other *nix programs use.
This bug WAS CONFIRMED as a bug.
This is very important in a multi-user work environment.
