I am interested to see if it is possible to boot on an existing disk -
say /dev/sda ("A") - and then manually create everything required on a
second disk - /dev/sdb ("B") eg:

- create the partition table and partitions on B

- dd the existing boot track(s) from A to a file and then dd that to B -
or create it from scratch somehow?

- rsync the the first level directories into the appropriate places on
the new drive and partitions (maybe by temporarily booting on a Live USB
so we are not copying from a running system?)

If this is possible, what else would need to be done on B so that when
drive A is removed, the remaining B (the new "A") drive will be able to
boot and run normally?


Presumably you would have to (at least)
1. Correct /etc/fstab
2. Install grub on second disk


Ah yes, of course . . I might give it a go . .

Thanks!

Phil.
