Comment 12 for bug 1007752

The cryptsetup isn't the same at all, since it specifies the crypt device in grub.cfg, and that is what you get on the kernel command line. Whatever grub.cfg says to pass is what gets passed and thus, what shows up in /proc/cmdline, which is why this isn't making any sense. I suppose when you reboot, it wouldn't hurt to hit 'e' and check... if it says sdq2 there instead of the UUID, then that would explain why /proc/cmdline is not as expected. The only way that it could differ at that point from what the cfg file says is if you somehow have a different grub install that isn't using that cfg file.
