Make users (like me) aware that the /quiet command will reboot the machine without intervention

For consistency, I suggest you to add those parameters into wmf/5.0/install.md as well. You could do this just by implementing changes in the "peterneave:patch-1" branch - they will be automatically added to this pull-request.

@zjalexander @joeyaiello - What do you think about this change? Do we need to add a reboot step?

[sdwheeler]

@peterneave Thanks for your contribution. I feel your pain about the reboot. But it is necessary. I talked this over with Zach. We will update the article to talk about the reboot. But I won't take this PR as is. I will have an alternate update to this article by tomorrow.
