This got discussed in Atlanta. There is a strong feeling /bin/sh shouldnt
be posix guaranteed (since only bash 2 and the commercial ksh are). Also
a lot of people like something small and fast running their default
scripts.

Suggestions included having a /bin/lsbsh for a shell that meets the
lsb specific definitions

Which BSD C-shell. The bugs vary by variant in very bad ways. Also
tcsh as csh shouldnt be acceptable. The quoting rules are different
and it causes security holes in things like metamail
