We're not rebooting for this, online migrations. GRUB install is the last step in the migration, it is already exclusively running on the new storage at this point.<br>

I can find no sign of any "device.map" file on the system and curiously, I do not need to do this on SUSE. You're saying create a new one, in the man page there is a --recheck command that says it deletes the file, nothing about generating a new one. Google is not very helpful regarding device.map. Maybe I could try strace'ing the grub-install command to find a clue. Or maybe if I can find it on SUSE I can compare... Some ideas for tomorrow.<br>
