Using ISO repositories in Ubuntu 9.10 Karmic Server

I found an ISO image on HP's support website that has a collection of
utilities to use with Ubuntu Server on HP Proliant Servers (ie DL360,
380). Rather than mess with FSTAB to keep the ISO permanently mounted
and available, I temporarily mounted the image and copied the
directory structure to my home directory like so;
sudo mkdir /media/isoimage
sudo mount /home/readability/HP_ProLiant_Value_Add_Software-8.32-6-2.iso
/media/isoimage/ -t iso9660 -o loop
cp -r /media/isoimage/ hprepo
sudo umount /media/isoimage
sudo rm -rf /media/isoimage

Now open Ubuntu Software Source list;
sudo nano /etc/apt/sources.list

And add the following lines to the end of the file;
deb file:/home/readability/hprepo/ karmic 8.32/non-free

Note that 'karmic' will correspond to whatever distribution you happen
(and the repository is for!) to be using (ie hardy, gutsy, jaunty) and
the term '8.32/non-free' is the path in within the repository below
the distro folder that leads to the folder for whatever version of it
you're using (ie i386).

Now update the source list;
sudo apt-get update
