The do_install step will fail to install the toolchain libraries unless you
have bash as the default shell. Making the default system shell bash hurts
boot time according to some data I have seen. Right now I used sudo
dpkg-reconfigure dash to make the default bash. Is there a better way? If
there is no better way, should the oe-layersetup.sh script do it for you if
$SHELL is not /bin/bash?

That's the correct way.

oe-layersetup.sh is distro-agnostic and should stay that way. Switching off 
dash is strictly Ubuntu-specific and requires root privileges, not something 
we'd want in oe-layersetup.sh...

There's a recent effort to get rid of bashisms in OE-Core and our layers 
(actually, if you chekc logs, you'll see some changes already). But for 
meta-arago to get full benefits of that, it needs to be upgraded from denzil 
to danny, which should happen soon.
