Ok. (Now, I recall the proof-of-concept thread from openstack-dev, and the ensuing discussions). > So a typical debootstrap might take 10 to 15 minutes : we build an equally vanilla image in 1-2 minutes. Oz has all the complexity of dealing with Windows and other esoteric operating systems Noted. 'debootstrap' reminds me of 'supermin' (similar for Fedora, written by Rich. Jones) http://libguestfs.org/supermin.8.html "Supermin is a tool for building supermin appliances. These are tiny appliances (similar to virtual machines), usually around 100KB in size, which get fully instantiated on-the-fly in a fraction of a second when you need to boot one of them." I did a quick test previously: http://kashyapc.fedorapeople.org/virt/openstack/supermin-fedora-appliance-building.txt >From a quick 'grep' through d-i-b sources, I don't see mention of 'supermin'. Maybe I should read more. > we do Linux and only things that can run in a chroot : so a much simpler and lighter weight tooling. Easy to debug (just drop into a shell), easy to customise (write some shell in a well known environment). Ok, I'm yet to try disk-image-biulder to understand how it creates things. I'm just giving diskimage-builder a spin on my F19 machine. (I personally am not really keen on windows either :) ) > > http://lists.openstack.org/pipermail/openstack-dev/2013-April/007185.html for instance is one thread about this on openstack-dev. Ah, right, I followed that thread but the content of your response slipped out my head. Right, some merits/demerits of using installer-based (anaconda/kickstart) / upstream-base iamge based. Thanks for your response. -- /kashyap _______________________________________________ cloud mailing list cloud@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/cloud
