/run is on tmpfs for most systems these days. It's ethereal and disappears whenever you reboot. The folders and files thereunder are recreated by the services that need them. $ mount | grep "/run" tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime,size=1639308k,mode=755) tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,size=5120k) tmpfs on /run/shm type tmpfs (rw,nosuid,nodev,noexec,relatime,size=3278600k) Chad
