Traditionally, "/sbin/reboot -f" would immediately call the kernel syscall to reboot, without contacting the init system, shutting down services, unmounting filesystems, etc. The man page for reboot/poweroff still says this is the case. However, it is not what actually happens with the systemd-provided reboot (just a symlink to systemctl). Reading the systemctl man page, apparently you have to add -f (or --force) _twice_ to get the traditional behavior. At a minimum, the man page should be updated, but it would be better to restore the old behavior (at least when systemctl is called as reboot or poweroff).
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.

Well, I wasn't sure if this was a good idea, since symlinking reboot/poweroff/halt binaries to systemctl seems distro-specific to me. I tried installing the current master into a temp directory and those binaries/symlinks are not there.
$ ls -l /usr/sbin/reboot lrwxrwxrwx. 1 root root 16 Oct 12 16:59 /usr/sbin/reboot -> ../bin/systemctl $ rpm -qf /usr/sbin/reboot systemd-235-1.fc28.x86_64 I'm pretty sure they are there ;)
Patch was reverted in https://github.com/systemd/systemd/pull/22518. It turns out that the original report was wrong and the original behaviour and documentation were correct and compatible with sysv halt.
