[Bug 1105147] [NEW] /etc/init.d/ondemand conffile prompt on upgrade to raring

[Steve Magoun]

Public bug reported:

I'm upgrading from quantal to raring. I got a dialog asking me whether
to replace /etc/init.d/ondemand. I don't recall ever customizing this
file by hand. Based on the diff (see below) it looks like the distro
conffile changed, so the upgrade should handle the diff silently without
prompting the user.
