Way back when I kept outgrowing the disk I had the OS installed on, that |
| 20 |
is what I did. I booted from a CD/DVD. I created the new partitions |
| 21 |
and such. I then created /mnt/old and /mnt/new. I mounted the |
| 22 |
partitions under the correct one, creating directories for boot, usr, |
| 23 |
var etc as needed on the new disk. Once all was mounted, I used cp -av |
| 24 |
/mnt/old* /mnt/new/ to copy things over. Today, I'd likely use rsync |
| 25 |
tho. If I had to interrupt the process, add the -u option. That worked |
| 26 |
then but not sure about now. |

I'd think UUIDs are always unique. I guess there is a 1 in a billion |
| 29 |
chance of a duplicate but doubtful it would be ran into by many. If |
| 30 |
nothing else, labels work as long as unique names are used. Using sda, |
| 31 |
sdb, sdc etc tho is a problem waiting for something bad to happen. |
| 32 |
Heck, nowadays one can even change the order drives are seen in the |
| 33 |
BIOS. I'm not sure about EFI stuff. I can make what is sda look like |
| 34 |
sdb without ever taking the side off my puter case or unhooking |
| 35 |
anything. Using labels or UUIDs eliminate that problem. |
| 36 |
|
| 37 |
In a way, things are more complicated. Thing is, if one uses UUIDs, and |
| 38 |
only them, it's really pretty simple. Copy and paste helps tho. One |
| 39 |
wouldn't want a typo. lol Of course, if one is careful, labels work |
| 40 |
just as well. |
