Public bug reported:

This is mostly annoying for armel/armhf.

lttng-modules-dkms ships a dkms.conf that contains the list of kernel modules to build at install time.
Unfortunately this list is dynamic, depending on the kernel configuration but dkms.conf is a static file.

This means that at the moment, installing lttng-modules-dkms on a system
that for example doesn't have kvm enabled will fail.

We should either find some option in dkms to ignore missing modules,
match all *.ko or have a pre-build script generating a new dkms.conf
based on the target kernel config.


I remember seeing this issue on 11.10 and it should still be there for 12.04, unfortunately my panda board currently refuses to build lttng-modules at all running 11.10. I'll try tomorrow with a clean Ubuntu 12.04 daily and will look into this bug then.
