Yes, I started a shell and moved it, and that would have been after
partman mounted /target, and before proceeding to the next step of the
install (I was in expert mode).
Behavior makes sense then.
It might be possible for d-i to do better in this situation, eg partman
could defer writing fstab until finish-install time.
What if other installer components or installed packages need to read or
write fstab ? partman-base provides "created-fstab" and some udebs
depend on it, so I assume they expect a populated fstab.
Besides, I do not think that it is worth to spend some effort to cope
with such an unusual situation. Users who tamper with the installer or
target do it at their own risk and should know what they are doing.
