Note to Mods: This Idea is NOT a Duplicate of Idea #14003
, which has been marked as "Already Implemented" (see below). The already implemented functionality is only available on the Alternate CD. This idea is to add the functionality to the Standard CD.
According to Ubuntu's Upgrade Notes
, the Alternate CD includes functionality to allow for upgrading from the CD, rather than from the repositories.
This functionality should be included in the Standard (i.e. "Live") CD.
This idea is in response to Idea #14003
being marked as "Already Implemented". Idea #14003
requested dist-upgrade-from-CD functionality be included, to which the developer response was "It has been possible since day 1. See https://help.ubuntu.com/community/UpgradeNotes
According to the linked Upgrade Notes, dist-upgrade-from-CD is available, but only from the Alternate CD.
Either the contributor for Idea #14003
was not clear enough, or - more likely - the developer who commented didn't consider that the vast majority of people do not know/think about/use the Alternate CD.
More importantly, while the Alternate CD is a logical place to have edge-case installation functionality, I think that one could make a strong argument that dist-upgrade-from-CD is not an "edge case".
Therefore, dist-upgrade-from-CD functionality that is available on the Alternate CD should be included also on the standard LiveCD.
