This is a design flaw of the FHS, which does not only affect cgroup but any software that needs variable runtime storage before /var is mounted. Afaik in debian using /lib/<package name>/ is an acceptable violation of the FHS to work around this FHS limitation. I would also like to have some opinion what to do in this case in general in Fedora. The package of mine that is affected by this is pam_mount, which includes a mount.crypt helper script to easily mount LUKS encrypted volumes. It needs to store additional information somewhere it used to use /etc/cmtab, but then moved to use /var/run/pam_mount/cmtab or similiar, which breaks mount /var using mount.crypt. But more importantly it may break umounting of partitions, because /var might be unmounted in Fedora before other mount.crypt mounted partitions were unmounted. At least this already happened with /usr being unmounted too early in the past. Regards Till
