This is a consequence of switching to the ALSA "dmix" device by default, which does transparent sound mixing in userspace via the shared memory. This fixes the extremely user-visible bug of multiple applications not being able to use the sound card at the same time. Fundamentally though the IPC key doesn't have to be allocated by the system; I wrote some code a while back that would have allocated it as part of the X login, all in the normal user session so there was no "system" part involved. I'm still not sure why our ALSA maintainer chose the ainit/PAM route given that you don't care about sound mixing for any other means of logging in like ssh or virtual terminal. Or at least, I don't think we should care. -- fedora-selinux-list mailing list fedora-selinux-list@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-selinux-list
