Since I maintain both dash and bash, I'm game for setting up /bin/sh as an alternative. However, I've never targeted the alternatives system before as a package maintainer; any advice on docs or an example that I could copy from? I would probably make the defaults give bash higher priority over dash, but with the alternatives in place, it would be easy for a local user to swap the priorities on their system; I'd probably also want to provide a convenience script to make swapping default sh an easier task than users having to actually call directly into the alternatives system. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
