The developers behind Systemd, the alternative to sysvinit, have added a mount tool to their user space bootstrapper. The mount tool landed during the weekend in this merge. It gives Systemd users a systemd-mount command, letting the mount command pull in dependencies and use auto-mounting logic. Developer Lennart Poettering notes, scheduling the mount means there's time to check parent mounts, or run a file system checker. Poettering gave a much longer explanation at Reddit, here.
