macOS 10.5 Catalina NFS Issues
If you’ve recently upgraded to Catalina and use NFS (for example by using Vagrant boxes with NFS mounts), you’ve likely experienced trouble like the following error message:
exports:2: exported dir/fs mismatch: /Users/youruser/Projects/Customer/Development/cms /System/Volumes/Data
In Catalina, user data has been moved to its own volume inside the main APFS

/System/Volumes/Data/ from now on. Given the above example, this yields:
/System/Volumes/Data/Users/youruser/Projects/Customer/Development/cms
