[03:11] <agrajag> Is the build system that makes the actual release ISOs distributed on ubuntu.com an open source project or is it squirreled away in connonical somewhere?
[11:24] <ogra_> agrajag, rootfses are built using live-build and livecd-rootfs from the archive ... image creation tools that use the rootfses are at https://wiki.ubuntu.com/ReleaseTeam/CDImageSetup
