Device reordering has been the bane of sysadmins existence for a long
time. I still remember when a Sun firmware (with a hardware intervention
by the vendor) update changed the order it scanned for scsi devices and we
got different c0t0's in the c0t0d0s0 addresses. I had to learn Forth to

you can also tell mdadm which dir it can scan for devices. it's been a
while, and is very limiting, but a quick google says DEVICE
/dev/disk/by-uuid/* and this corresponds with my recollection. granted
that was centos5.

I wasn't mdadm'ing, so i usually use the fs uuid. if you want the device
uuid, it'll need to be that guy and not using ID_FS_UUID. but it's pretty
basic down at that level, so as long as you keep your layers right, you
should be able to find the thing you want to bind to.

I'd add that if your students want to learn linux well, they should use one

To avoid swap wearing out your ssd, if you don't have an hd handy, you can
set vm.swappiness to 0. This is not great since paging is quite efficient
these days, but sometimes you'll want swap for suspend operations and don't
want to actually page unless you're under memory pressure.

the implementation of math.sqrt could take advantage of anything specific
