What is the reason for that? There should be a comment explaining why.

There is no need to “sign-off” your own commit; this is only done by
committers who push a patch on behalf of someone else.

Version 2.13 is available; any reason for not using it?

There is no need to set #:parallel-tests? if #:tests? is set to #f.

Any reason for the labels not being the same as the package?

While running the configure script, I get

configure: You may configure with --enable-python-bindings if you want Python bindings.

So you would have to pass the ‘--enable-python-bindings’ flag, and
Python would be needed during runtime as well.

I would use @code{lttng-ctl} and @code{lttng-relayd}.

The bottom of the homepage says

…LTTng-tools is licensed under LGPLv2.1 and GPLv2…

so it would be (list license:gpl2 license:lgpl2.1)

Could you send an updated patch?

Would require to bump version of lttng-ust also I think. I prefer to do all of this
in another patch.

During my testing, I noticed that test in parallel are not working
because of how the lttng-daemon works. So I disable the parallel option
in order to not forget it when testing will work in the future. I
should probably add a comment to explain the rationale here.

I follow the naming convention in the description of the project's README
so it's easier to map the dependencies described by it to Guix's
packages. I can change this, but I find it more clear that way.

Does it tho? Bindings can be generated at build time. While you would
require python-3 at runtime to use the bindings, you don't require
python-3 to use the other tools of the project. I don't mind adding it
to the inputs, I'm just asking.

The name of the label is usually the same as the package, so I would
change them to “kmod” and “module-init-tools” respectively.

True, the user can install always install Python in their profile
themselves.

Applied!

I noticed this:

Toggle snippet (8 lines)
$ strace -f -o ,,s /gnu/store/dyx2cwfv85d02bdhbvi1l8wqrxya7gdk-lttng-tools-2.12.5/bin/lttng --help

IWBN if you could follow up with a patch that changes /usr/bin/man to
the right absolute file name.

Thank you!
