I now have autologin root direct to desktop working via the usual systemd override tricks. It is pretty straight forward and well-explained, with subtle alternatives, on the Internet (for examples, google: autologin root agetty systemd; for example, the Gentoo page on this is instructive and for startx too; the X without Display Manager page in Gentoo wiki also gives a neat trick for starting alternative desktop managers depending on login tty being used).
Despite the opinion of some others, I myself find systemd superb to use in practice despite being no expert in its configuration. Void Linux runit is almost as good, though I'm not quite so familiar with runit having spent a couple of years using WDL_Arch, which also used systemd (autologin/startX is somewhat less complex to arrange with systemd than with runit, albeit very similar). The advantage of systemd is partly the way you can use simple override file under /etc/systemd to modify existing service file; unlike with runit, there is no need to create new special getty service for tty1 and disable the original - just creating the override file does it all.
Whilst I will put that autologin-to-desktop feature (as root by default) into rc2 release I might on my own system remove the autologin part (but keep the auto-startx part). For (admittedly basic) security reasons (even at home!) I rather like manually logging in with password to root, or spot, or firstrib, or whoever I've added as user to my system. However, autologin as root to desktop is the usual for most on this forum, so by default, despite the even more security conscious, that is the form rc2 release will take. It does work well in my tests and avoids the added bloat of a login display manager such as lightdm.
Having said that, without some further configuration trick, the shutdown Logout choice would automatically re-login back as root user to desktop without the option of ever then logging in as spot or firstrib... I will therefore endeavour to provide a userswitch menu choice such that you can re-login as spot or firstrib instead... That might do me as well, rather than actually disable automatic login (except I prefer my own system to need a login password). The way KLV-Airedale does logout to new login prompt is fine actually.
As I said before, I will also fix up some of the minor issues I noticed on publishing rc1. I doubt that I'll actually be adding much to the base system since keeping that one pretty much as it is, with these 'fixes' is really my plan, but with the idea that KLU-jamCE version will thereafter be released to include whatever the Kennel Linux community agree on.
I will also explain on release of rc2 how to remove the autologin facility if you so choose (but can keep the auto-startx part of the mechanism if you wish). Most I expect will probably want to keep full autologin to desktop capability though.
