If a directory has a sticky bit set, it will change the group ownership of any file created in that directory to the group owning the directory. If my understanding is correct, the group ownership should only be changed if the set-group-id bit is set on the directory permissions, not the sticky bit. Note that the user ownership is correct, and that the set-group-id bit works as it should. If I am out in left field on this, I apologize for bothering you! >How-To-Repeat: >From your favorite command shell -- $ mkdir stick $ chmod 1777 stick $ su - # chown root.bin stick # exit $ cd stick $ touch file $ ls -l and you will see that "file" is owned by the group "bin", not the user's group. >Fix: Unknown, though I suspect a small little typo somewhere. :) This problem is easy to work-around, though a bit annoying. >Audit-Trail: >Unformatted:
