Thanks for the review.

Bear in mind that the issues you raised are orthogonal to the FTBFS fix,
although they are of course valid.

I don't know offhand.  As you can see from the logs "make check" is
being properly invoked by the dh_auto_test target, and "make" is
traversing the tree and calling "check" on the subdirs as expected, but
for some reason all of them return with "Nothing to be done for
'check'."

Looking into the "tests/" directory, we can see that there's not much
there.  I did find what looks like to be valid tests inside
scripts/augeas/tests/test_nut.aug, but I don't know how they're supposed
to be run.

I checked that the same problem obviously happens on Debian, and I
verified that the Fedora nut package doesn't run its tests during build
time either.  The next step would be to build a pristine upstream
checkout and verify what happens there, I guess.

Yes, this package unfortunately suffers a lot from mismatches in the
symbols file.  I've had my fair share of headaches dealing with it last
year...

The last upload from doko added the "optional=lto" flags so that it'd be
possible to build the package with LTO.  I don't intend to fix this
issue here because it's unrelated to the FTBFS, but it's something to
keep in mind next time we merge the package from Debian.

Thanks,
