Where do fluxbuntu and xubuntu come in on this scale?

Where do fluxbuntu and xubuntu come in on this scale?

First, darrelljon, nice listing. I might add a few to this list :

1. Slackware, several distros in your list are based on it ...
2. What about an Ubuntu minimal install ?
   
   http://kmandla.wordpress.com/2007/04...art-to-finish/
   https://help.ubuntu.com/community/In...wMemorySystems
   http://www.psychocats.net/ubuntu/minimal#barebones

Fluxbuntu is now in Beta testing (the betas are NOT public atm) with a planned release hopefully in sync with ubuntu 7.10

It will weigh in very close to the "under 256 Mb" (alternate install disk)

The primary advantage of fluxbuntu is compatibility to the Ubuntu repos.

Often this is the greatest disadvantage with a number of these distros is the relatively small repos potential lack of security updates. Fluxbuntu will have a significant edge here ...

EDIT: Last I looked ELive is Debian, there are two Ubuntu distros with e17 : geubuntu and elubuntu

Elive is a complete operating system for your computer. It's the perfect choice for replacing your proprietary, high-cost system. It is built on top of Debian GNU/Linux and customized to meet your needs for a complete operating system while still offering the user eye-candy, with minimal hardware requirements.

Just a note on Fluxbuntu. I read the fluxbuntu review on tuxmachines and although it is only 300Mb image, it seems to struggle with 256Mb RAM let alone 128Mb RAM (which I'd like to be the threshold for inclusion). Is this true, because the website suggests as little as 64Mb RAM, and should it go on the list?

I would put it on the list. I put Fluxbuntu on a 450Mhz K6-2 with 256Mb and memory usage was less than 128Mb. I know a lot of the bugs are still being ironed out, but it's very polished and quite impressive.

A lot of folks are pinning their installation experiences and system profiles on here ...

[darrelljon]

As I understand it, Fluxbuntu is still in alpha development, and Xubuntu isn't as fast/lightweight as any of these, even including SAM which is the biggest.

[Shazaam]

How about adding floppy based distributions? Or would that make the list too large?

[darrelljon]

If any had a remotely friendly graphical desktop environment with a few graphical apps, I'd consider it. This is quite a tall order for floppy based distros and only KolibriOS really manages it.

[K.Mandla]

http://www.minix3.org/

Minix3 is probably worth mentioning, although it's not really Linux either, and it might take some very specific hardware to install. I've tried on a couple of computers but had no luck. Looks like the ISO is around 300Mb.

[darrelljon]

Fixed eLive from "Ubuntu based" to "Debian based", ta.
Minix looks quite daunting for average users from the screenshots. Is it even stable yet?
Slackware is 3Gb.
Ubuntu minimal install looks good, but is more a customisation of Ubuntu (that can't be specifically downloaded) than a ready made distro.
I'd like to add the 2 floppy Basic Linux (but can't find screenshots of it anywhere), KolbriOS CD version and a compilation of FreeDOS+OpenGEM Complete perhaps (but can't find it anywhere).
