You mean you reboot without running  'sync' command?

And yes - on reboot you should properly unmount devices - so you should
see removal of target on your shutdown sequence -  I believe Fedora currently
tries to support switch to some shutdown ramdisk, so all filesystem and
devices might be properly unmounted and destroyed.
