Miroslav, I think we need a policy for sa-update running out of cron jobs. I added a preliminary policy to F16. Fixed in selinux-policy-3.9.16-39.fc15 selinux-policy-3.9.16-39.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/selinux-policy-3.9.16-39.fc15 Package selinux-policy-3.9.16-39.fc15: * should fix your issue, * was pushed to the Fedora 15 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing selinux-policy-3.9.16-39.fc15' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/selinux-policy-3.9.16-39.fc15 then log in and leave karma (feedback). selinux-policy-3.9.16-39.fc15 has been pushed to the Fedora 15 stable repository. If problems still persist, please make note of it in this bug report. Running:
selinux-policy.noarch 3.9.16-42.fc15
selinux-policy-targeted.noarch 3.9.16-42.fc15
This is not fixed. Sorry I didn't notify earlier.
Here's what I'm getting with setenforce 0:

This seems to include some stuff that I reported before, and some stuff I didn't; I don't know why.

It is perhaps worth noting that this time I actually let cron run it (after commenting out the sleep line in the cron script). -Robin Fixed in selinux-policy-3.9.16-43.fc15 selinux-policy-3.9.16-48.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/selinux-policy-3.9.16-48.fc15 Package selinux-policy-3.9.16-48.fc15: * should fix your issue, * was pushed to the Fedora 15 testing repository, * should be available at your local mirror within two days.

I simulated the run like this: sudo runcon system_u:system_r:system_cronjob_t:s0-s0:c0.c1023 sh -c "/usr/share/spamassassin/sa-update.cron 2>&1 | tee -a /var/log/sa-update.log" (that's from cron.d, and takes Quite A While to run) with enforcing turned off.
