This is required so that the mount options of these file systems -- which are pre-mounted by the kernel, the initial RAM disk or system manager code -- are updated to those listed in /etc/fstab. This service ignores normal file systems and only changes the root file system (i.e. /) and the virtual kernel API file systems such as /proc, /sys or /dev/. This service executes no operation if /etc/fstab does not exist or lists no entries for the root file system or the kernel API VFS. systemd1, fstab5, mount8
