I'm concerned there might be issues with kernel 4.15 in bionic that would change the expected output.

Could you check and confirm that even the oldest kernel (in that case 4.15) is still delivering valid messages on the initial problem "loading a non existing module while aliases don't exist".
If it behaves different with 4.15 the solution for Bionic needs to be more complex :-/

review: Needs Information

[Rafael David Tinoco (rafaeldtinoco)]

Yep, will do and post it in the bug and mention here for you.

Done. I think its safe to drop for 4.15 as well.

* Removed --add-udeb from dh_makeshlibs, since libkmod2-udeb does not
  actually contain a library. (Closes: #939779)
  (backported from debian version 26-2)

[Rafael David Tinoco (rafaeldtinoco)]

Could you give a +1 for this last change as well ? This guarantees that the package actually builds with current dh_makeshlibs. It is based in a change made in Debian at version 26-2.

[Christian Ehrhardt  (paelzer)]

As I said on IRC:
for your 4.15 check - don't you need to remove /move the .alias. file?

[Rafael David Tinoco (rafaeldtinoco)]

Yep, I did:

"""

Testing Bionic kernel with the initial situation the bug being dropped said to fix:

(k)rafaeldtinoco@bkmodissue:~$ sudo rm /lib/modules/4.15.0-91-generic/modules.builtin.bin
(k)rafaeldtinoco@bkmodissue:~$ sudo depmod -a -F /boot/System.map-4.15.0-91-generic

ok

(k)rafaeldtinoco@bkmodissue:.../4.15.0-91-generic$ sudo mv modules.alias.bin modules.alias.bin.old

(k)rafaeldtinoco@bkmodissue:.../4.15.0-91-generic$ sudo modprobe hehe
modprobe: FATAL: Module hehe not found in directory /lib/modules/4.15.0-91-generic

and it is also safe to drop it based on previous bug test case

Thanks for checking +1 now
