Detailed Description

Current location

/var/lib/rpm 
/var/lib/dnf

New location

/usr/lib/sysimage/rpm 
/usr/lib/sysimage/dnf

Benefit to Fedora

The RPM and DNF databases describe the state of (primarily) /usr. Storing these databases in /usr will more easily facilitate OS rollback, without affecting /var.
