I've added "--autologin sebaro" to the agetty command for the first tty and put these in ~/.profile:
https://wiki.gentoo.org/wiki/X_without_Display_Manager#Starting_X11_on_console_login

It works for both OpenRC and systemd, the issue is when rebooting/powering off with OpenRC, it keeps restarting X until it reboots/powersoff.

Hmm...interesting.

Traditionally there should be a temporary "/etc/nologin" file to tell login to prohibit logins during shutdown/reboot, but it seems to not use this during the actual reboot (or --autologin ignores that fact).

You probably can work around this fact by checking the current runlevel and don't startx when it's trying to reboot or shutdown. /sbin/runlevel or 'who -r' will tell your current runlevel. Look in /etc/inittab for "id" for the default runlevel and only startx when the current runlevel matches the default runlevel:

Code:
if [ $(who -r|awk '{print $2}') = $(grep ^id: /etc/inittab |cut -f2 -d:) ]; then
echo starting x11...
startx
else
echo not in normal runlevel due to reboot or shutdown, sleeping...
sleep 30;
fi


(actually I'm not sure this works, and thinking that there might be a race condition on boot-startup. YMMV. Probably best to detect if it's in either reboot or shutdown and don't startx when in these cases.)

systemd probably simply "works" because of some other mechanism as things are more tightly integrated together.

That's the solution I've been thinking about.
The problem is that '/sbin/runlevel' and 'who -r' don't work because I'm using openrc-init as init not sysvinit.

OpenRC stores the runlevel in /var/run/openrc/softlevel but I'm not sure how accurate it is.
This seems to be working fine so far.
Code:

if [[ -t 0 && $(tty) == /dev/tty1 && ! $DISPLAY ]]; then
   if ! grep -q "shutdown" "/var/run/openrc/softlevel"; then
     exec startx &>/home/.session.log
   fi
fi

This should be working too:
Code:
if grep -q "default" "/var/run/openrc/softlevel"; then

The startx issue seems to be solved but I've found the same issue with autologin. It repeats until agetty is stopped.
