Hi Thierry, I think it is an excellent idea to put a link about your sagedebianlive on the sagemath homepage. I think the easiest way is to contact Harald Schilly directly about it. It would also need an improvement of the existing documentation about the purpose of the different images. I am aware that probably the need of classic "Live CD" images is rapidly declining, while USB/Flash card based images might have their niche in the future. I can stick with the puppy base which is optimized for this purpose, but it would be better to bundle efforts and work on a common base. Last year I tried to test your image but I ran into some difficulties (size, download time etc.) and personal time constraints, so I abandoned it. Over the last year there appeared some efforts to develop a system based on pure debian live with full apt-get ability in the puppy community. Recently a substantial "slimm down" of the official debian base was reported (there is a JWM desktop squeeze image with 65 MB, and a wheezy ICE WM desktop image with 150 MB), so building a really small debian live image with sage became realistic for me. Light Debian Live Squeeze, <http://www.murga-linux.com/puppy/viewtopic.php?t=90586>Light Debian Live Wheezy <http://www.murga-linux.com/puppy/viewtopic.php?t=90660>, How to reduct the size of Debian Live Image<http://www.murga-linux.com/puppy/viewtopic.php?t=90629> Currently I build a proof of concept image, I intend to keep the base and the sage build seperated in 2 different squashfiles. Technically the Debian base has far more rough edges (networking, wireless, keyboard settings, as you already mentioned localisations) and it lacks all the fine small puppy apps, but it has the big advantage of the working package management. For me the best overall concept would be to offer a small working base image, and offer the additional software (e.g. texlive, but also maybe Modellica or OpenFOAM) prepackaged in squashfile modules. The distribution off the whole software bundle on one stick would still be possible, but additionally it would be possible to download a small working base for testing etc. Currently I boot a frugal hd install of the squeeze version, and I have a live-rw storage file for my persistent changes ( Iuse GRUB4DOS bootloader) title Light-Debian-Core-Test root=(hd0,3) kernel /live/vmlinuz boot=live config persistent nonetworking swapon quickreboot noprompt autologin initrd /live/initrd.img boot I am still unsure of how to build sage, I guess I will use debians atlas package and also debian compilers and try to make microlrelease. I think there is a lot going on in https://wiki.debian.org/DebianScience/Sage, so maybe there can be a far more integrated build in the future.
