While trying to repair yet another botched Ubuntu upgrade, I got this fabulous warning message:
Do you want to continue? [Y/n/?]
The following ESSENTIAL packages will be REMOVED!
sysvinit
WARNING: Performing this action will probably cause your system to break!
Do NOT continue unless you know EXACTLY what you are doing!
To continue, type the phrase "I am aware that this is a very bad idea":
I was rushing through, so a simply Y/n prompt probably would have left me screwed (still my own fault) – but this one pretty much slams you in the face with how bad a move you might be about to make. And you just know that there are people on message boards complaining that this broke their system.
It reminds of this school I did work for at my old job. When they insisted on buying and maintaining their own firewall, rather than going through us, we made them sign a document explaining how that was entirely 100% their machine to deal with and we were not responsible for supporting it at all. Sure enough, as soon as they had problems they said something to the effect of, “We know we signed that document absolving you of responsibility, but we still think this is your responsibility.” Sometimes spelling it out just ain’t enough…
But how nice of them to give you the option of breaking your system, that is, if you really wanted to.
