Sorry, which FD are we talking about?

I presume you're talking about a command sequence like this:

# unshare --mount
# test-fsmount
# mount --move . /mnt
# mount --move /mnt /mnt
# cd
# umount /mnt
# exit

but this fails on your modified test-fsmount with:

shell-init: error retrieving current directory: getcwd: cannot access
parent directories: No such file or directory
