Description of problem:
Found this while using a live of Fedora 26 Workstation (20160416 compose), during the installation of the system on a qemu/kvm guest.
SELinux is preventing systemd-localed from 'write' accesses on the file /etc/.#vconsole.conff67jvQ.
***** Plugin catchall_labels (83.8 confidence) suggests *******************
If you want to allow systemd-localed to have write access on the .#vconsole.conff67jvQ file
Then you need to change the label on /etc/.#vconsole.conff67jvQ
Do
# semanage fcontext -a -t FILE_TYPE '/etc/.#vconsole.conff67jvQ'
where FILE_TYPE is one of the following: afs_cache_t, initrc_tmp_t, locale_t, puppet_tmp_t, user_cron_spool_t, xserver_etc_t.
Then execute:
restorecon -v '/etc/.#vconsole.conff67jvQ'
***** Plugin catchall (17.1 confidence) suggests **************************
If you believe that systemd-localed should be allowed write access on the .#vconsole.conff67jvQ file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'systemd-localed' --raw | audit2allow -M my-systemdlocaled
# semodule -X 300 -i my-systemdlocaled.pp

Proposing as a blocker for Fedora 26 Final.
The notification of SEAlert popped up (together with other 2/3 AVCs) after reaching the 100% of the installation of Fedora 26 Workstation.
This seems a violation of the "2.5.4 SELinux and crash notifications" criterion
"There must be no SELinux denial notifications or crash notifications on boot of or during installation from a release-blocking live image, or at first login after a default install of a release-blocking desktop."
https://fedoraproject.org/wiki/Fedora_26_Final_Release_Criteria#SELinux_and_crash_notifications
Discussed during the 2017-05-01 blocker review meeting: [1]
The decision to classify this bug as an AcceptedBlocker was made as it violates the following blocker criteria:
"There must be no SELinux denial notifications or crash notifications on boot of or during installation from a release-blocking live image, or at first login after a default install of a release-blocking desktop."
