And you patch the sources of that module to contain a Makefile that does what you want. Henning Am Tue, 27 Sep 2022 15:20:57 +0200 schrieb "Roberto A.

I confirm you that this approach do NOT work for the 3rd party modules I have to compile in ISAR against a standard debian kernel. I accept to be a newbie in ISAR but the only approach that demonstrated being working with this stuff is exorcism as root!
