After reboot sdx could be sdy, as you noticed.
The solution: you dont access a drive via /dev/sdx
You access per UUID and the kernel maps it to the appropiate sdXY which
could be sdy after reboot.

I am not sure about initial ramdisks etc. maybe there is hardcoded stuff
to sdx in there. Maybe it has to be rebuilt? Maybe you has to rebuild
initrd as well as updating fstab?
Kind Regards, Markus Falb
