Ubuntu – the difference between the alternative and desktop cd images

installationiso

I would like to know what the difference is between these two versions of the same distro.

ubuntu-10.10-alternate-i386.iso    
ubuntu-10.10-desktop-i386.iso  

I think that the alternative CD is not Live,
but is there any more to it?

Best Answer

Yes. The alternate CD comes with all the Ubuntu packages (and so can be used as an upgrade package source by simply running apt-cdrom add). The desktop CD has all those packages already installed as part of the squashfs image, which is convenient for doing new installations, but unusable for doing upgrades with.
