Re: Patch to enable reboot/shutdown from within the session

Alkis,

Rather than edit the LDM scren script, which I believe should never be
done at this point, I would rather we do this:

Create an "Init" script in the ldm/rc.d directory that does what you
propose.  Something like:

/usr/share/ldm/rc.d/I00-haltreboot :

case "$(cat /tmp/ldm-logout-action)" in
        REBOOT)
            exec reboot -fp
            ;;
        HALT)
            exec shutdown -fp
            ;;
esac

-Gadi
