Hi Björn,

thanks for testing it!

Only for the serial tty init.  But it might be similar here too, I don't know.

According to https://elixir.bootlin.com/linux/v3.2/source/include/linux/kd.h#L70
that's trying to clear the Unicode -> font map (that is, charmap).

In Linux, ./drivers/tty/vt/vt_ioctl.c implements it.

Can't see how that ever ends up in -EIO O_o

Please, anything *but* 3 fractional places.

Right now, it's still possible to disambiguate "," and "." errors--that would
not be possible with 3 fractional places.

After this release, let's integrate an installer.

wip-installer-2 works fine.  The architecture could be more generic (it has
peculiar ideas about how any installer screen MUST look), but it's not bad
or anything.  Also, the wizard leaves something to be desired (I didn't
find the place where it does that yet: You can select any future step, but
if it requires information in a dependent step, it will instead jump to
that one - that's jarring and not what you would expect - at least not
without good visualization).

I thought about doing fully generic Guile window management library a la
Turbo Vision but it's really overkill for what we need.  Nice, sure.

I think the technical holdup for merging wip-installer-2 to master was the
modularization of guix.

Also, I've packaged Anaconda, the Red Hat installer.  It still fails some
tests (and has a lot of dependencies).  I would need some help with Guix's
gi.repository handling.
