Oh, OK.

I have:

--8<---------------cut here---------------start------------->8---
$ dmesg |grep -E '(udevd.*starting|Conso)'
[    0.000000] Console: colour VGA+ 80x25
[    3.750956] udevd[190]: starting version 1.10
[    4.536397] Console: switching to colour dummy device 80x25
[    5.421016] Console: switching to colour frame buffer device 170x48
--8<---------------cut here---------------end--------------->8---

I don’t think we can solve it generically without adding udev and all
the graphics drivers to the initrd, can we?  Or perhaps we could just
include a few common graphics drivers by default?

Excellent.  I was thinking that we should have a keyboard layout setting
in the OS declaration, that would lead to a service like the one above
as well as the appropriate X settings.

Yeah, that could be nice.

I wonder how this should work.  Currently we’d have to start one dmd
instance per user; I’m not sure where/when this should be started.
Also, should the global OS declaration include user-specific service
lists?  WDYT?

Thanks for your feedback!
