I've been forced into using systemd under Arch, so I'm relishing the 
opportunity to get back to a more sysvinit'ish init system under Gentoo. I 
decided to go with

# TERMINALS
c1:12345:respawn:/sbin/agetty -a mythtv --noclear 38400 tty1 linux
c2:2345:respawn:/sbin/agetty 38400 tty2 linux
c3:2345:respawn:/sbin/agetty 38400 tty3 linux
c4:2345:respawn:/sbin/agetty 38400 tty4 linux
c5:2345:respawn:/sbin/agetty 38400 tty5 linux
c6:2345:respawn:/sbin/agetty 38400 tty6 linux

(as found at https://wiki.gentoo.org/wiki/Automatic_login_to_virtual_console)
and [[ $(tty) = "/dev/tty1" ]] && exec startx
in .bash_profile as found at https://wiki.gentoo.org/wiki/Start_X_on_login

After reading "To put things in perspective, after accounting for shared 
libraries that you need to load for other parts of X/MythTV, the 
incremental cost of running FluxBox is less than 1MB of RAM. The 
incremental cost of running RatPoison is only 300KB. If your system needs 
that 1MB or less of RAM, that's not all the RAM it needs (so you're better 
off getting more RAM than trying to run without a Window Manager)" at 
https://www.mythtv.org/wiki/Frequently_Asked_Questions#Do_I_really_need_a_window_manager_for_a_frontend_only_box.3F, 
I decided to just go ahead and go with evilwm. My .xinitrc (still 
untested as the system is STILL compiling) is:

cat .xinitrc
xsetroot -cursor_name top_left_arrow
xsetroot -solid black &
exec /usr/bin/evilwm -term xterm &
mythfrontend > /home/mythtv/mythfrontend.log 2>&1

Thanks, Rich.
