Yes. It is missing the package net-tools.
I wasn't aware that systemd-sysv is also missing. But it may be the reason
of some issues in my minimal system.

Ok, then Charging is still broken. Once I have finished upstreaming the
tsc2007 patches so that we get a precalibrated touch I should submit the
twl4030-charger patches.

Hm. This can be a lot of things. Maybe X11 config.
Do you see a /sys/class/backlight entry?
