    Use compat.linux.emul_path instead of hardcoded path in /etc/rc.d/linux
    
    In /etc/rc.d/linux the mounting paths of procfs, sysfs and devfs
    are hardcoded to "/compat/linux".  Switching to the content of
    compat.linux.emul_path sysctl would allow to switch linuxulator
    to different place.
