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.

I think a lot of people who write scripts have gotten used to the fact that
/bin/sh -> /bin/bash and assume that that's how it's going to be in all
systems. It isn't a bad idea to explicitly add #!/bin/bash if you wish to
use BASH functionality.

I'm running ubuntu 6.10 on my box, with /bin/sh pointing
to dash, and thus far I've not had any serious problems.
If you have specific failures, I'd love to know about them,

The same for me. Everything's running fine.

Greetings:

I spent the entire evening trying to reproduce the problem and could
not.  I was having problems in the binutils build.  It was failing to
compile the documentation.  I'm willing to chalk it up to some other
problem with the 6.06->6.10 upgrade.  I lost the unifdef package
somewhere in the upgrade process, but removing it didn't cause the
problem to come back, so that wasn't it.

Sorry to waste everyone's time.
