I don't like much nested includes like this. It makes it much harder to
know what is or is not in a config.

I think what we want it more kernel config fragments (e.g. GENERIC.pci,
GENERIC.fs, GENERIC.network and so on) to be inclued in real config files,
not one config file including one other.

If we go this way I think it would be better to have XEN0 include XENU and not
the opposite. There would be less things to remove.

The error is to have WSDISPLAY_* options in XENU. There's no wscons in XenU.

No. This doesn't work and should be removed.

"required for xentools20" ? :)
