Hmm I’m not sure this is true.

On current ‘wip-installer-test’
(0699b97f7df8708a000eb7bfb043c2cef6672dc3), you can run:

  make check-system TESTS=gui-installed-os

(It should succeed.)

If you take the /gnu/store/…-installation item produced and mount it as
I showed before in this thread, you should see a “recovery complete”
message from the kernel.

Note that LUKS is not involved at all in this case, and ‘umount’ doesn’t
throw.
