I need to create minimalistic server appliance for running on amazon ec2 (ami). I tried debootstrap. its coming upto 200+ MB , its same with vmbuilder also. Are there any ways of getting it down to 100MB or less.

I just need it with bare minimum linux os + JRE. The smaller the size the better.

Any Suggestion

Regards

You might want to try Gentoo Linux, it's as minimal as you can get. –  Oxwivi Feb 19 '11 at 8:27

You could try starting with just the Ubuntu minimal image, found here. Building up from the 10Mb ISO should give you enough flexibility to keep the size down as much as possible.

Jeos (Just Enough OS) has been discontinued now - it's only available with the old 8.04 version. This document, highlighted by Marcello Nuccio in the comments below, demonstrates that Jeos itself is now replaced by a combination of using vmbuilder and the minimal install. Quote : "With vmbuilder, there is no need to download a JeOS ISO anymore".

JeOS is not discontinued, it is no longer available as a CD-ROM ISO for download, but only as an option either: while installing from the Server Edition ISO; or to be built using Ubuntu's vmbuilder. –  Marcello Nuccio Aug 25 '11 at 3:39
    
Well now. That's a great demonstration of how poor the Help WIKI is. Go here : help.ubuntu.com, type "Jeos" into the search and try to find anything that might suggest Jeos is still an option. –  Scaine Aug 25 '11 at 9:37
    
Refined my answer to summarise my findings. Thanks for the link Marcello. If you do that search I mentioned, then click on the "Official" refinement, then your link is the first hit. Just a shame that the community docs are so misleading. –  Scaine Aug 25 '11 at 9:44

this tutorial provide a idea to solve it. It uses vmbuilder, a python script that enables you to generate your JEOS in cli.
