Bug#960688: fwupd: missing Breaks: fwupdate (<< 12-7)
Let me elaborate the timeline.
* Originally fwupdate contained /usr/bin/fwupdate.
* It was merged into fwupd and fwupdate went into maintenance only mode.
* In Debian we made fwupdate a transition package with nothing in it.
This is when the Replaces got put into place.
* Because it was a transition package, there is a chance that a user already
removed /var/lib/fwupdate and so a request was put in for fwupd to clean that up.
* Later, a compatibility binary /usr/bin/fwupdate was added into fwupd.
This performs similar actions as the old fwupdate provided /usr/bin/fwupdate.
Hopefully that illustrates the timeline. As fwupdate is a transition package now,
I don't know that it makes sense to add the Breaks now, please advise.
