The export is fine, as live-initramfs takes care of doing the right thing then.

This is strange and definitely some kind of error, but I've never seen this so
far. What does the log on your FAI server say about the mount request?

There are parts that need to be written on every boot-up, just temporary things.
Prior to live-initramfs this was solved by mounting parts of the file system as
tmpfs. Now live-initramfs takes care of everything.

You definitely need to debug the mount problem, possibly by checking the logs on
the server.
