Follow-up Comment #6, sr #110656 (project autoconf):

> dash is much less portable than bash, due to its very incomplete autoconf
Oh, I meant only that dash _once working_ should be a better shell to use for
running 'configure' and similar shell scripts on the 3b1, since dash should
use less memory and CPU than bash.

If dash's Autoconf script is incomplete for the 3b1, perhaps you can contact
dash's maintainers and see if they'd be willing to accept patches that would
port dash to the 3b1.

Another possibility is to tune Bash so that it uses less memory. This could be
something as simple as running its configure script with --disable-nls
CFLAGS='-O2' etc., or by having a new compile-time option that you invent that
makes tables smaller or omits other Bash features.

Either of these approaches might mean less work for you in the long run (it
depends on how long-run your needs are).
