    rc.conf.5: note that a negative nice value does not reach a service jail
    
    Raising a process' priority is not permitted inside a jail, and nice(1)
    warns and executes the command anyway, so the service comes up at its login
    class priority.
    
    Not changing the date, as a commit a moment before this, one changed it
    already.

    (cherry picked from commit be834d62e990b58eb2e67ce9b48b635b645dcea1)
