Comment 11 for bug 2017786

@eeickmeyer - the version of the change that actually landed in the package essentially adds the following to the update script:

+if ! which germinate-update-metapackage >/dev/null; then
+ echo >&2 "please install germinate"
+ exit 1
+fi

I think this is a useful improvement as not everyone has germinate installed but do as you wish with your packages.
