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

https://github.com/Piraty/void-packages xbps-src-zap
https://github.com/void-linux/void-packages/pull/15437

xbps-src: (zap) correctly empty the masterdir
Instead of relying on a potentially outdated list of files and dirs to
remove, just remove+recreate the whole masterdir.

This previously led to leftover .xbps* files, which broke subsequent
operations.

See: #14476

A patch file from https://github.com/void-linux/void-packages/pull/15437.patch is attached
