[Pkg-xen-devel] Bug#376494: xen-utils-3.0: Bashisms in /etc/xen/scripts/* make Xen unable to run domUs

[Roberto Suarez Soto]

Package: xen-utils-3.0
Version: 3.0.2+hg9681-0bpo1
Severity: important

	Disclaimer: I'm using the packages from www.backports.org here
(in the box where the problem manifested), but I've seen that it happens
too with the packages straight from sid.

	When I installed the packages for Xen and created a domU
("chen.cfg"), it couldn't be brougth up. The error that was displayed
was:

~# xm create -c chen.cfg
Using config file "/etc/xen/chen.cfg".
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.

	Checking the logs, /var/log/xen-hotplug.log was full of lines
like this:

trap: 53: ERR: bad trap

	I am using dash as /bin/sh, and this is the problem. I've not
checked in detail, but it seems that there are bashisms in the scripts
at /etc/xen/scripts that cause this failure. Changing /bin/sh to
/bin/bash fixes the problem.

	The solution would be changing /bin/sh to /bin/bash in the
scripts, or at least warning the user that /bin/sh needs to be /bin/bash
in order for the scripts to work.
