The way rpm-(OSTree) is designed is that the /var directory is owned by the daemons and system administrator. Upgrades and rollbacks will never affect it. Now, many daemons need empty directories in /var. rpm-ostree contains code to automatically synthesize systemd-tmpfiles snippets for them. For these packages, a nicer thing to do is to stop shipping the directory (perhaps with a %ghost entry). However, anything with non-empty regular files will not work. The best solution here is to modify the code to not depend on one. For example, glibc ships a /var/db/Makefile. This could be replaced with a symbolic link to /usr/share/glibc/db/Makefile. Or alternatively, suggest that administrators do: make -f /usr/share/glibc/db/Makefile
