Right now updating is just replacing a package, right? But replacing a
package that is virtually the entire system might result into complicated
issues. I guess Haiku.hpkg could be handled differently by haikuDepot or
whatevere else could be used for updating but, as it is, the user can still
manually overwrite haiku.hpkg with another one.

This is exactly the type of issues I have in mind. Tracker could be
replaced without a reboot. So could deskbar. So could some drivers...
Replacing haiku.hpkg will most likelly always require a reboot.
