I've got it now. Apparently /usr has needed to be available at boot

'user', and that /usr contains only applications and not system
software. We learn something every day: whether we want to or not.

I can see that I'm not going to be upgrading my server next time, but
rebuilding from scratch, as it has a /usr partition and isn't on LVM.
At the very least, it's a partition rebuild onto another drive. Oh, joy.

As I understand it:

For many setups, separate /usr will work because those setups don't tickle the things that cause problems.

For *any* setup, you can make separate /usr work by using an initrd and ensuring that all tools which will be needed before /usr is mounted are included in the initrd image.
