as far as I see, nothing happens... but... somehow, "something" does
happen. The same done with tmpfs... surely provides me with a nice
message, that my kernel lacks support for tmpfs as you did assume too. I
did disable tmpfs in the kernel because I did not need it.

Anyway, thanks for the hint. I did enable tmpfs again and the package
installed correctly. I am not aware of the general package guidlines,
but maybe you should add a check wether tmpfs is enabled or not which
prints a related message to the screen if it is not enabled rather than
just aborting the installation due to the lack of tmpfs support.

best regards
Michael
