Kmod

Kmod

So finally, kmod compiles without linux/module.h. However, it fails its tests.
I am attaching the testsuite.log as well as the patch, if someone feels like
working on it; I will not have time in the foreseeable future. By the way,
the tests also fail when I compile by hand on my debian system, not only
in the guix build environment; so maybe it would be enough to simply file
a bug report.

Thanks for working on it!  That looks good.

I wonder if the test suite is supposed to work when run as non root.

I’ll see if I can investigate by next week or so, but it’s even better
if someone else does.  :-)

Re: Kmod

[Ludovic Courtès]

I’ve pushed a variant of this patch, but I confess I haven’t yet taken
the time to investigate on the test suite failure (the priority for me
being to get udev running.)

I’ve also pushed udev based on preliminary work you had emailed me.

Thanks,
Ludo’.
