Comment 1 Dangyi Liu 2015-11-09 06:19:09 UTC 
On Fedora 23 this bug is more severe because kdump cannot start even with bundled kernel.

$ ls -Z /boot/vmlinuz-*
          system_u:object_r:boot_t:s0 /boot/vmlinuz-0-rescue-9e1725064a94497289316879f51a108f
          system_u:object_r:boot_t:s0 /boot/vmlinuz-4.1.7-200.fc22.x86_64
system_u:object_r:modules_object_t:s0 /boot/vmlinuz-4.2.5-300.fc23.x86_64
Comment 2 Dangyi Liu 2015-11-09 08:14:54 UTC 
This bug is caused by that kernel-install didn't handle file context properly after copying bzImage. It has been fixed in http://pkgs.fedoraproject.org/cgit/systemd.git/commit/?id=d4f265678413c7656d78074af12ec7f083b50aac , but hasn't been merged into f23 branch.
