Re: REISUB vs. RSEIUB
The R is the acryonym is to switch the input modes. It hasn't been needed in most of 10 years. We're already in that input mode.

E and I are going to cause a lot of activity on the disk as processes close and do final writes and everything. As you can see, sync before E and I is pointless.
U is for forcibly unmount. Unmount implies a sync operation. So now that S is really pointless. In fact, there's no difference between SU and U, so anyone that tells you "Do REISUB, not RSEIUB" is still wrong. U and SU are the same.
B means to immediately reboot the system.
So what do you need to type in? AltGr + Sysreq + EIUB. That's it. Nothing more. So naturally I type and teach RSEISUB. Why? "Raising Skinny Elephants Is So Utterly Boring" is something I find really easy to remember, and who cares if you're doing extra syncs or switching to an input mode you're already in?
