[nmglug] Freezing

[Ted Pomeroy]

Brian, A quick look at it seems that it is correct. Swap is a partition, it
has to be unmounted to be re-sized, hence the 'swapoff' command. The 'dd'
to resize it is an interesting approach, rather than using parted or
gparted. If you have used all of the physical drive to install, it might
feel clearer to use gparted to enlarge /swap and see which other partition
is giving up some room. Check to see if the sample directions were
installed to hardware like yours or was it a virtual install? I will have
to take a look at the discussion on the Internet. Thank you, Ted P.
