Re: lm-sensors vanished

[Andreas Enge <andreas@enge.fr>]

More on lm-sensors, which we will probably need for installing the hydra
replacement: First, the input rrdtool is not referenced in the output; could
it be moved to native-inputs, or maybe even dropped? I tried a compilation
without it, and it succeeded, but I did not yet check whether the result
actually works.

Second, it is extraordinarily big, which means we cannot reasonably add it
to the installation image, and then it will take a long time to download
during the installation:

Perl is needed for two scripts:
bin/sensors-conf-convert, which
"Convert[s] a sensors.conf file from the old (Linux 2.4, lm-sensors 2)
symbol names to the new (Linux 2.6 or 3, lm-sensors 3) symbol names."
and which is probably not important for GuixSD.
And sbin/sensors-detect, which I think is needed.

Could we maybe drop gnuplot, which seems to pull in a lot of X related
packages?
