This patch was referenced by an issue (https://github.com/openwrt-routing/
packages/issues/547#issuecomment-586213155), but original author was not
able to runtime-test. In Freifunk Berlin we also don't use the pud-plugin and
can't therefore not confirm it.

I just opened PR #575 to mark this package as broken, till there is a 
maintainer again ...
