Indeed. If there were any differences that I had not already edited to account for and the result of grub2-mkconfig were not *exactly* what is already in the file. > Even the UUIDs ? Yes. I copied the filesystem byte-for-byte, (i.e. dd if=/dev/sda5 of=/dev/sda7; followed by resizing the filesystem on /dev/sda7), not just the files in it. I then changed the UUID of the filesystem on /dev/sda5. > > Too bad. Indeed. > You could put /boot in LVM I used to be a fan of that in fact. I think I finally gave up fighting distro installers that refused to allow you to do that due to the distros' fears of /boot in LVM. I think I recall that also became problematic when the LV became fragmented due to extending it without space on the disk being available directly subsequent to it. > So just check if the /boot partition number changed after > any > other partition change. That's an interesting tidbit. I don't think I have ever witnessed this renumbering of extended partitions personally. Not saying it doesn't happen. I have just never experienced it myself. I do tend to stay the hell away from partitioning though and only use it to the extent that I need to bootstrap LVM onto a machine. Indeed on every disk other than the boot disk, the entire disk, with no partitions on it is an LVM PV. Cheers and thanks for all of your help. I have my machine booting without trouble now. b.
