Busybox build problem

[Ravi Chemudugunta]

the posix nazis will want you denis =)

I think its noble of dash adhering to posix standards (whatever they are for
shells) ... as you mentioned the base for bash is too big to 'cleanup' to
work with dash...I would have all scripts by default run on bash, unless
explicitly defined inside the scripts...for e.g. leave sh pointing to bash
but inside the shell scripts which are 'cleaned' ... have them execute
against dash with #!/bin/dash or fork dash that is like bash
(grammatically).
