I deploy ubuntu on multiple clients computers every day, currently I use 14.04.2 iso. After installing it I do `apt-get update && apt-get upgrade -y` which takes some time.

Is there any 14.04.x iso which has the latest upgrade, so `apt-get upgrade` don't find any new packages?

My plan is to download this iso once a week, so at most I will download upgrades of a single week on each computer.

Mainly I am looking for ubunutu; but if there is for lubuntu, kubunutu and xbunut it will be great.
