Mounting a partition at /var wouldn't work with system containers. System containers are stored in the OSTree storage and on Atomic Host they are checked out to /ostree/deploy/$OS/var/lib/containers/atomic/ so that the checkout and the OSTree storage are on the same file system. This is required to use hard links instead of copying files from OSTree. Regards, Giuseppe
