FYI, the B20 version of ASH has a number of bug fixes over the B19
version.  If there are specific problems that people would like to
submit fixes for, we'd be happy to apply them.

Also, FYI, the ash that we're using comes from Debian.

So far a number of the problems that I've seen have been complaints that
ash doesn't work like bash.  That's exactly right.  Ash is meant to
emulate /bin/sh.  /bin/sh != bash.

Pointing out that ash has "several serious bugs" does not really give
us enough information to work with.
