This probably isn't going to work the way you want. Starting the share1
automount will itself cause share0 to be mounted, since systemd needs to
ensure that the share1 directory exists, and to mount an autofs
filesystem at this directory.
If you stack automounts in this way, the "inner" automount essentially
keeps the "outer" mount permanently in use.
I've created the unit files for .mount and .automount for the two shares,
with mount disabled and automount enabled and started. This seems to work
fine once the system is booted. But the share1 automount fails to start on
boot with the error "dependency". The share0 automount is started and works
when the mount point is later accessed, but not the share1 automount.
I don't know what to add to satisfy the boot-time dependency of
srv-share0-share1.automount.
From the boot log, it looks like the system is trying to actually mount
these shares. But the server they're being mounted from may not be up yet
when both are powering up together. That's why I'm using an automount.

So what's happening here is that systemd is trying to mount share0, which
is failing...
Mar 26 18:29:14 saruman systemd: Dependency failed for Automount NAS1 share1.
Mar 26 18:29:14 saruman systemd: Job srv-share0-share1.automount/start failed

... which means it can't start the automount inside it.
