There's a merged pull request on the void-packages repository

New package: seatd-0.4.0
https://github.com/void-linux/void-packages/pull/24580

Description:
~~This is not ready to be merged as upstream does not yet version the shared library files. Also, tests are currently patched out due to build failure in release mode (this is already fixed upstream but unreleased).~~

~~The only consumer of this daemon/library is the wlroots master branch as far as I know, so it doesn't really make sense to merge before the next wlroots release anyways.~~

Edit: this is good to merge

I expect that seatd will become a popular alternative to elogind on void linux, so I've made this preliminary package to facilitate early testing.
