Well, I agree it is not the normal case :)
I was testing my own custom installer that uses (somewhat modified version
of) base-config, and doing different silly things to see what will
happen. So I found this issue, and thought that it may raise in
unmodified version also (like other issues I recently reported on
base-config).
Maybe, when /usr/sbin/base-config is started manually, user may press
<Ctrl-C> after entering invalid data once, and symlink will be left
broken.
On the other hand, it will be absolutely harmless to create the link
several lines later, after successful mount, when it is guaranteed that
data is valid.
