Resizing a partition

[JohnD]

I now have played back my backup image of LL's home directory:

1. I've build a new partition in the same place with GParted.
   
2. I've copied the backup image with [tt]dd[/tt] to the partition.
   

In fact I do use currently LL again. But I've failed to resize the home partition -- until now.

My oldest computer, it was in around year 2000, it is a P4 1GB ram, I use LL 2 series (late in 2 series).

My system is this:
