Device names are by definition somewhat arbitrary and should never be
relied upon. For example, if you boot your system with an USB key
plugged-in, the kernel might very well decide to assign /dev/sda to the
USB key, shifting all other device names by one letter.
Mounting by label is a good alternative, but you can also mount disks by
ID or UUID (using /dev/disk/by-*/ device names).
