The NFS utils store their state under /var/lib/nfs and they can
generally handle the case where that directory is missing by creating
the appropriate files and directories automatically.
This is not the case of rpc-statd: if sm and sm.bak (under $statdpath,
which also defaults to /var/lib/nfs) are missing the daemon will
refuse to start and will exit with an error.
If nfs-utils is configured with systemd support it can take advantage
of systemd-tmpfiles to ensure that the state directories are always
present and have the appropriate ownership.
This would normally be handled with the StateDirectory directive in
rpc-statd.service, however that method would not be able to change the
ownership of the directories to $statduser because this daemon needs
to be run as root, and only later changes its uid and gid.
