Yup, the day we have a shelll tested out, which does not break
too may packages.

No, we have to do is ask a few questions first:
a) Is it required we break out of this circle? (I suspect there is a
group that shall aver, quite vocally, that this is indeed the
case). What are the benefits of not using bash (some of these have
aready been pointed out to the list)
b) Is there an tested alternative? We don't know yet. I think we
should test this. try out a different shell. If we all try out a
few cnadidates, we should soon have an idea about which ones are
viable (pdksh, ash, etc ...)
c) How many packages need to be changed?
d) can we create an upgrade path by which people can safely ugrade to
a non-bash /bin/sh? Are there any known glitches? (guessing is not
e) does the benefot of all this work really justify the work?
f) How many non-Debian packages are affected? Does this affect user
scripts, and if so, to what extent?
