    rc: Bring in a simple mechanism to run rc scripts only once.
    
    The basic mechanism is: If /firstboot exists, rc will also run all
    scripts that have the "firstboot" keyword, then delete /firstboot.
    
    This is a simpler version of FreeBSD's work. Specifically, we hardcode
    the firstboot sentinel's name to /firstboot and we also remove it a
    bit more simply because we assume that at the end of /etc/rc, root is
    R/W.
    
    This mechanism is used for example by sysutils/ec2-scripts and is in
    preparation for the upcoming ena(4) driver import.
    
    Based-on: FreeBSD
