[ale] what should I do when resizing ext4 partition

[Brian Mathis]

You can resize a normal partition by deleting it and then making a new one
that's bigger, as long as you start the new one in exactly the same place.
I'm not sure if any gui tools allow you to get that precise, but fdisk will
do it just fine. (Of course, you always want to have a backup)
