Comment 2 for bug 71887

OK, yet another thing that breaks horribly with dash being the default-shell: XEN precompiled packages.
It took me ages to find out that dash was the reason things broke that bad.
IMO it is a really bad idea to switch the default shell to dash by default. I have no problem with the possibility to set it to dash (dpkg-reconfigure works, but update-alternatives would be more intuitive).
