    Add systemd sigrtmin3/container compat to runit; customize pkg versions. · 763c8ead
    David Johnson authored
    systemd has a behavior that is very nice for containers.  If you send it
    SIGRTMIN+3 (37 on some Linux systems), it will halt the machine (see
    https://www.freedesktop.org/software/systemd/man/systemd.html).
    Further, if the env var "container" is set, systemd will actually exit.
    
    9001-systemd-sigrtmin3-compat.diff adds this functionality to runit.
    Prior to this, runit would of course just sit and spin after entering
    stage 3 (its halt/shutdown/reboot target).  Now if the env var
    "container" is set, runit will exit.  Plus runit can be signaled by
    Docker (or whatever container manager) to shutdown immediately via
    SIGRTMIN+3.
    
    (Also, this commit adds the custom "emulab" bit into the package version
    strings.)
