Hi Ronald. The basic idea is that >= macOS 10.15.1 Apple has made most of the filesystem read only on a folder by folder basis. They separate user-writable onto a separate filesystem, treat it like a disk, and they mount it under /System/Volumes/ as "Data". Likewise, I think the idea is that other volumes get mounted under /System/Volumes, however, since "/System/Volumes/Data" is now "firmlinked" to root, I imagine you can find mounts to the writable filesystem under "/System/Volumes/Data/Volumes" which firmlinks to /Volumes.
