[Leaplist] gparted and KVM quetjuns'

[Whit Hansell]

Hi Kevin,
Thanks for the reply.  Maybe we're having a terminology problem here.  I 
have in the past taken 250M from /dev/sda9(/home) and moved it all the 
way down to /dev/sda1 (/) because in the past, after I had set up the 
system, I was doing dist-upgrades and there were security changes to the 
kernel and the original setup did not give me enough room on /(root) to 
set up the new/changed kernel.  So had to make it bigger.  I used 
gparted 0.3.4.x at the time and it worked fine.  I'm just trying to 
remember just how I did it.  Whether I took the needed space from sda9 
and set it to unallocated between sda8 and sda9 and then hit "apply"  
and then allocated the unallocated to sda8 and hit "apply".  Or set up 
instructions for gparted to "move" the space from 9 to 8 and then hit 
"apply".

As I said, I have done it before and it worked.  Just don't remember how.

As to LVM and your recommendation.  Unfortunately, I don't  have the 
time to go thru all that.  I do have my box set up to dual boot two 
drives, one Debian and one XP.  I was just thinking of having it all on 
one drive and using it w/o rebooting.

I had looked at using wine but figured the new virtualization was/is the 
way to go now so wanted to take a shot at it.

Anyway, thanks a bunch for your recommendation.  Maybe at a later date 
or on another drive, I'll try to set it up and learn it then.   Again, 
thanks.
Whit
