Salut Jean-mathieu,

I finally found the strange bug.
The kernel package from buster backports breaks if the version of the
wireless-regdb package from stable is installed. This is what happens
in your config because the Gnome enviroment or the nonfree firmware
will install wireless-regdb from stable.

It's very hard to get the correct package list in this special
situation. Therefore I found a simple fix, which adds wireless-regdb
into the backports config.

The technical details are more complicated and not in FAI itself, but
IMO this workaround is simple and works. A test using a new FAI.me
image showed no problems now.

regards Thomas
