Subject: [ABRT PATCH] daemon: allow only root user to trigger the post-create
|
|
|
8ec399 |
|
|
|
8ec399 |
There is no reason to allow non-root users to trigger this
|
|
|
8ec399 |
functionality. Regular users can create abrt problems only through
|
|
|
8ec399 |
abrtd or abrt-dbus and both triggers the post-create.
|
|
|
8ec399 |
|
|
|
8ec399 |
Other hooks run under root user (CCpp, Koops, VMCore, Xorg).
