Looks like my extra mounts cause that delay, I disabled them and delay was gone. Not sure what has changed after builds 1021 or 1022 (not sure which one) since this has worked fine before.

It's the systemd-235 update in #1021.

We're aware of the issue (but were not aware of any delay until your post), and it will be fixed (just not sure when).

Can I downgrade to older testbuilds without problems?

Yes, downgrading should work just fine.

Here is one of my mount files:

Thanks. As I say this will be fixed eventually - unfortunately systemd can be a PITA to debug and fix.
