We got some warnings on the autobuilder, as no maintainer is assigned to the emptty-conf recipe: WARNING: emptty-conf-1.0-r0 do_recipe_qa: QA Issue: Recipe emptty-conf in /srv/pokybuild/yocto-worker/a-full/build/meta/recipes-graphics/emptty/emptty-conf.bb does not have an assigned maintainer. Please add an entry into meta/conf/distro/include/maintainers.inc. [missing-maintainer] https://autobuilder.yoctoproject.org/valkyrie/#/builders/29/builds/1515/steps/13/logs/stdio Can you fix this on the next iteration please?
Sorry, but we probably have two more issues on the autobuilder related to this series.

Can you have a look at these failures please?
From: Randolph Sapp <rs@ti.com> We've recently run into some issues with weston-init attempting to start Weston prior to all drm devices being registered. There's not really a good, scriptable mechanism to listen in to device registration events that works with the existing weston-init package. Well, at least one that doesn't involve polling files or introducing more dependency on the init system being used. I also see there is also a lot of scripting around starting X11, xserver-nodm-init, that (from my limited review) should experience the same issue. I'd like to introduce the following display manager for oe-core, emptty [1]. This display manager is, as described upstream, a "Dead simple CLI Display Manager on TTY". It supports both x11 and wayland sessions, with togglable build parameters to completely remove x11 and pam dependencies. It's licensed MIT, which shouldn't be an issue for any users. (It is written in Go, if you have opinions about that.) With this, both weston-init and the xserver-nodm-init packages can be re-tuned to leverage this display manager and simply add a user and emptty config for an autologin session. This can resolve the current behavior across init systems without additional scripting, and move some development out of this layer. This lists myself as a maintainer of emptty as well as xserver-nodm-init and xuser-account since these are currently unassigned and I've reworked them significantly here. Sorry for the delay on this series. I found a few bugs in emptty that I wanted to address before submitting this officially.
