Yes. I don't want to be guilty of the "Bike Shed Effect", here
(http://linuxmafia.com/~rick/lexicon.html#bikeshed) in my haste to kibbitz,
but that one thing (the "rm") stuck out at me as something avoidably
dire and irreversible, if one _does_ happen to care about existing
sources.list contents and doesn't notice their deletion until too late.
