Comment 4 for bug 1723183

I've seen this before, I can't remember how we fixed it there. I believe it should be fixable by using .mount units directly (instead of relying on systemd generator to convert fstab to .mount units) or by adding more ordering/deps between these by using x-systemd* options on the ftab lines.

it somehow does handle nested root mounts badly by default. Because it assumes that to mount /media/root-ro/ one needs /, and it cannot grasp the concept of nested / (as in subsequent mount is mounted on top of /)

in general dependency cycles are bad, and should be fixed. I'll play around with this.
