Manual approach might be confusing and prone to errors. |

I will try Gparted as you suggested but I was wondering if it will allow |
| 40 |
me to combine/join partitions. On most modern system I think there is: |
| 41 |
1 - boot partiton |
| 42 |
2 - swap if needed |
| 43 |
3 - root partition (where home is as well) |
| 44 |
|
| 45 |
My current layout is old one: |
| 46 |
dev/sda1 /boot ext2 |
| 47 |
/dev/sda3 / ext4 |
| 48 |
/dev/sda2 none swap |
| 49 |
/dev/sda4 /home ext4 |
| 50 |
|
| 51 |
Is it possible with Gparted combine "/" and "home" partitions, or is it |
| 52 |
as simple as coping all file from "home" partition to "/" home folder. |
