Added an instance if what recovery is attempted if error unwind itself
runs into problems.

Cleaned up some of the language in the /etc/init.d script output
formatting.

Cleaned up the command -v example. Instead of the massively complex
shenanigans suggested in the bug report, just use which. which lives
in an essential package, so can be used in the preinst of packages.
