We generally document shutdown(8) instead of reboot(8) as it's better for interactive use. In modern FreeBSD is matters a lot less, it's mostly just convention. One minor thing is that shutdown(8) produces a global message, while reboot(8) does not. It is believed that historically, some versions of reboot did not do appropriate safe shutdown checks and just rebooted. It's also just consistency: for example the handbook[1] documents shutdown. There is actually another important difference between reboot and shutdown -r now: reboot does not run /etc/rc.shutdown. This is because reboot has its own shutdown procedure and does not signal init like init 6 and shutdown -r now do (except in the case of rerooting via reboot -r). A few years ago jilles@ proposed changing reboot's default to signalling init (preserving reboot -q which just invokes the reboot system call), but this was not accepted. Perhaps this can be tried again for 13.0.

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
