Greetings:

Just a warning to the buildroot users.  The newest Ubuntu (6.10 -
released 10/26) has modified /bin/sh.  In previous versions /bin/sh was
a link to bash.  In the newest version it is a link to dash, a smaller,
limited function shell based on bash that Debian developed to use on
their boot floppies.

Dash is missing a lot of functionality that bash contains, and I've been
having a lot of trouble building using it.  Ubuntu's claim is that dash
is a POSIX shell and that if you needed the additional functionality of
bash, you should have used #!/bin/bash instead of #!/bin/sh as the
header in your script.

In any event, just changing the /bin/sh link from dash to bash fixed all
of my problems with no noticeable problems on the workstation.  If
you're having problems building on a Ubuntu 6.10 system, that's a good
place to start.
