Simple Linux ACL problem... I must be missing something
In playing with ACL (Ubuntu 22.04 LTS) I'm immediately running into a problem.
As me:
$ touch /tmp/foo
$ setfacl -m u:test_user:rw /tmp/foo
$ getfacl -p /tmp/foo
# file: /tmp/foo
# owner: me
# group: me
user::rw-
user:test_user:rw-
group::rw-
mask::rw-
other::rw-
So far so good.
Next, I log in as test_user
$ cd /tmp
$ getfacl foo
# file: /tmp/foo
# owner: me
# group: me
user::rw-
user:test_user:rw-
group::rw-
mask::rw-
other::rw-
...still good.
But now (still as test_user):
$ echo something >> foo
sh: 4: cannot create foo: Permission denied
$ echo something >> /tmp/foo
sh: 4: cannot create foo: Permission denied
The same happens when I create the file foo in my own (home) directory instead of in /tmp (I tried that first and when that did not work I figured I'd try /tmp)
What am I missing? Why can test_user not write to the file?
