The bug log has an alternative suggestion regarding just making the
preinst use a /bin/bash shebang, on the basis that bash is still (and
probably always will be) essential.  This seems so simple that I'm sure
there must be a catch somewhere; I just haven't worked out what it is
yet. :-)

I'd prefer if we could find a solution that DTRT here without requiring
intervention from users.  Noting the manual solution in the release
notes wouldn't be the end of the world, however.

LINENO isn't part of the SUSv3 Shell Command Language as specified in
Policy.  The description of the variable therein explicitly states that
it "specifies the effects of the variable only for systems supporting
the User Portability Utilities option" and Policy does not require UP to
be supported.

In any case, this issue is resolved in squeeze and sid already.
