   The update process will usually restart server processes immediately,   
   although AFAIK this is something each package has to do at least   
   somewhat independently, so presumably mistakes can happen.   
      
   Apart from that, once an update completes, new executables (and   
   libraries etc) are available to run immediately, but they will only   
   start running next time something executes them.  For example if you   
   update Bash, existing logins will be unchanged but new logins will get   
   the updated shell.   
      
   There?s no time-based delay.

   I think that?s basically right. An update to init (usually meaning   
   systemd now) may require a reboot before it takes fully (not sure), but   
   apart from that there?s very little that inherently needs a reboot.
