Why does abrt have to write file in /var/lib/rpm? I would like to lock down this domain as much as possible. I don't want it running rpm directly. I would rather have it only able to execute debuginfo-install and that is it. I do not have a problem with it running rpm to figure out what packages are installed. But if as a user I can get abrt to install stuff via crashing some apps, this concerns me. Weird, as far as I know, abrt doesn't write anything directly to /var/lib/rpm, we use debuginfo-install for installing debuginfo rpms. We only use rpmlib directly to READ some info about package, certainly not for writing. rpmlib probably tries to create a lock file, but it should be allowed. Jirka I don't think it does. When you use the rpm python bindings it does an access check to see if the database is writable, which is causing the problem. I have this dontaudited in selinux-policy-3.6.32-16.fc12.noarch |
