[opensuse] why /var/run and /run these two directories have absolutely the same contents?

i know /run is a new cross-distribution location for the storage of transient state files, and /var/run is replaced by /run. but 1, why /var/run still have contents just as the same as /run ? just for backward compatibilty ? 2, if a program want to write some data to /run, is it supposed to write the same data to /var/run ? 3, it seems /var/run is not a symlink to /run, so /var/run occupy harddisk space, just like /run does? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
