Just got idea from this(may not be related though) question however.
Are the ISO images from the official site updated with updates in Core Ubuntu system , like Kernel Updates , desktop Environment Updates(unity), i mean Updates of BASE system including X-org, Office suite, Package Manager , Update manager or Gnome Base Modules, those released in update Branches like precise-Updates branch.
The reason i am asking this is , if i download the ISO image of Ubuntu 12.04 Say after two or three months from release , i have to do an update of approximately 200~300 MB's size.
So why are these ISO images not updated to recent updates, i am aware that all of the components are not updated at the same time , but let's say after One month from actual release ( Both LTS and normal releases), the updated components can be added to form a Updated ISO in regular intervals, which provides new users to use latest versions and features with improved stability and less bandwidth Consumption.
I am not mentioning the idea of comparison to Rolling Release , or External PPA's added updates , and neither Netinstal but the ISO of updated Packages .This can be provided as optional download.
Since my question is within the boundary of Official updates releases so stability could not be the reason. I guess there are custom packagers out there , but having an official option would be better.
It helps in distributing Newest ISO OS which impresses a lot new users , since it makes availability of newer features and a faster system ofcourse. Another reason of asking this is here.
Edit: Since almost all new (Desktop) users download the Default ISO's having one or few issue , which may have been corrected in following updates. But most of new laptop users i encountered gave up because of it , so should i suggest ,for laptop not listed on Certified H/W list , to try daily Builds , if needed.
