Here is a sample log messages: May 4 05:00:01 wolff crond[16709]: (bruno) NULL security context for user, but SELinux in permissive mode, continuing () I didn't save the original selinux attached to __default__. It might have been user_u; it definitely wasn't unconfined_u which is what I got with a fresh install on another machine. Besides fixing up the login user mapping, I also fixed up the user mapping to prefix, mls level, range and roles. There were several new selinux users that weren't in the list I got after the upgrade. Once I have everything matching that of the fresh install, I stopped seeing the NULL security context messages. I can't say I expected that the upgrade would work without manual intervention when going from FC5 to F9. But I would have liked to have gotten some hint that I should look at things. And if I hadn't had another machine with a fresh install to compare against, having some way to do that on a machine would be nice. Normally things stick *.rpmnew files in /etc, but I suspect that would encourange people to copy it over rather than using semanage to update things, so that may not be a good solution for selinux. -- fedora-selinux-list mailing list fedora-selinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-selinux-list
