Redundant distro branches

[Daniel van Vugt]

Wait a sec, is there really "going to be trouble"?

I am reminded that the landing on the train branch (lp:mir/ubuntu) is 
always the _last_ thing to happen by far. lp:ubuntu/mir and 
lp:ubuntu/wily-proposed/mir as well as the archive itself with shiny new 
debs all get updated around a DAY earlier than the final landing to the 
dummy branch (lp:mir/ubuntu) happens. It's annoyingly delayed, so that's 
hard to forget.

Therefore, I doubt that using lp:ubuntu/something for the train to 
monitor would cause trouble at all. Worst case is that it tries to land 
the same branch twice. And we all know from previous experience that bzr 
blindly succeeds and shows no diff landing any branch multiple times. I 
think it would just work.
