The reason is following: The RUN is /var/run in multipath-tools. When we start linux, we mount a disk to /var. So if multipathd.service start before mount, it will fail to activate.(If mount firstly, multipathd will start successfully) The RUN is defined in Makefile.inc: ifndef RUN ifeq ($(shell test -L /var/run -o ! -d /var/run && echo 1),1) RUN=run else RUN=var/run endif endif Can it always be defined as run?
