There is a new pull request by CameronNemo against master on the void-packages repository

https://github.com/CameronNemo/void-packages NUT
https://github.com/void-linux/void-packages/pull/24265

network-ups-tools: do not ship binaries in /var
In Debian these are shipped in /lib/nut,
which is equivalent to /usr/libexec/nut on Void.

Binaries certainly do not belong in /var.

A patch file from https://github.com/void-linux/void-packages/pull/24265.patch is attached
