udev rule in /etc
this is what lintian says (e.g. https://arm01.puri.sm/job/debs/job/deb-librem5-devkit-tools-buster-aarch64/127)
E: librem5-devkit-base: udev-rule-in-etc etc/udev/rules.d/99-gnss.rules
this ought to be in /lib/udev/rules.d/
(and also in librem5-base
rather than librem5-devkit-tools
)
