Bug#754423: adapting rc.local that needs interaction to systemd

[積丹尼 Dan Jacobson]

OK what anybody used to do in /etc/rc.local can all be now often also be
done instead via making a non-symlinked
/etc/systemd/system/getty.target.wants/getty at tty1.service and changing

# ExecStart=-/sbin/agetty --noclear %I
ExecStart=-/sbin/agetty --noclear --autologin root %I
# Restart=always
Restart=no

And then at top of root's .bash_profile put
r=my.rc.local
t=/tmp/.ran.$r
if ! test -f $t
then sh $r && touch $t && kill -1 $PPID
fi

Then one doesn't need to learn any new protocols!

My only regret is this leaves a dead tty1.

I would like instead to leave what looks like a login: prompt there on
tty1, just like one sees now on tty2 etc.

That is I need a way to write something like
ExecStartFirstTime   =-/sbin/agetty --noclear --autologin root %I
ExecStartAllRestTimes=-/sbin/agetty --noclear %I
Restart=always

It is not clear on man systemd.service how to do that!
