It only does direct mounts, not indirect mounts, and it's all designed to be trivially simple to use (i.e. just add "comment=systemd.automount" to your fstab options), pulling in no further deps for this, and integrate well with the rest of systemd, i.e. doing the full dependency mumbo-jumbo as soon as an automount is triggered. The idea is that it "just works", is tiny, and makes autofs something you want to use without having to think about NIS or LDAP or other configuration maps. (yeah, I know, you don't need NIS/LDAP to configure maps in autofs.) automounting support in systemd is attractive for a number of reasons. The main one is that it allows us to cheaply establish mount points without having to back them with real file systems right-away. That means we can leave the early boot phase much earlier than we traditionally could, since we don't actually need to wait for fsck/mount to complete for all file systems listed in /etc/fstab. This allows us to parallelize fsck/mount and daemon start-up in a fashion previously not possible. This is not necessarily particularly interesting on general purpose systems but on embedded systems it is.
