There is also usermode LXC. Whith it you can arguably get a pretty good security too, roughly comparable to KVM or even better. UML still is more secure, since it should be more immune to privilege escalation via kernel bugs.

To put it simply: one layer of ECC simply isn't enough on nowadays' storage sizes. See the link on the @SteveWills answer.

It is all about the errors that gets uncorrected by the disk's firmware. If the firmware didn't correct for the errors, the error rate would be many, many, many orders of magnitude worse than 10^(-14).

I think your answer is too long and convoluted. If you feel the answer needs to be that long, try to add some headings that would guide the attention of the reader. I have problems myself in understanding your points. BTW it wasn't me who downvoted you answer.

comment Why does sudo su -l user -c bash fails to load user's environment?
sudo -u adam "command" works! I kind of assumed that under upstart's root sudo would lead to the same error as su. I still understand nothing, but I am grateful it works! Thank you!

comment What is the reliable way of getting each user's .ssh directory from bash?
It is a default, that can be changed in /etc/ssh/ssh_config and sshd_config; at least on Ubuntu 14.04

Great answer with all the polishing that includes the awk magic (which I never truly understood)
