The default installer on the current GameOver iso requires a minimum of 8GI don't think it's correct. I used to make testing installation for every sparky version before uploading to a server.
I never set more that 2 GB of RAM and no SWAP even for GameOver. It's really strange what you said.
As said in the other thread, the "new" installer, which is the default, copies the files from the installation media to /tmp before mounting the partition you tell it to install to. /tmp is backed by tmpfs, which is limited to 50% of your system's memory (possibly including swap) at most, and the files are ~4G in size, meaning you need ~8G memory to hold them. However, if this problem doesn't exist in testing....Is there logic in the code that's supposed to do this in certain cases? If so, removing said logic (and just having the installer copy directly from the installation media) would probably be for the best, even if it makes some edge-case installations slower.
If you installed Sparky 32 bit version, simply install linux-image-686-pae. It will solve your problem.
Anyway I could add the second (686-pae) kernel to the existing 486 on next live iso so I did ones before.
But the problem is with the iso image limited space.
I understand about space constraints and compatibility, and I'm quite sure that some folks with very old systems will be grateful for your choice. Folks with newer systems, however, need to be made aware that the 486 kernel is what's used on 32-bit sparky, and how to switch kernels to one that will better suit their needs, especially since a 32-bit OS is generally better for gaming atm. I'm on the fence about updating, since I have a single-core system, which makes me question what if any performance gain I would see out of the 686 kernel, and updating would require me to fix nvidia again (which should be relatively easy).
One other thing to add to "The Bad" above: PulseAudio is installed by default. I know, I know....PA is required by at least Gnome (and maybe KDE as well now, but I'm not sure) now for desktop sound effects, is installed by default by all but one major linux distribution and a very small handful of minor ones, and tends to make sound work better when it does work, but I've never had anything but trouble out of it, so it's always the first thing to go when I set up a system that has it by default. YMMV (If the problem I have were completely ubiquitous - which it's not - or PA was painful to remove properly, I would rate PA as "The Ugly" - the problems I have with it are that bad).
Edit: Finished a thought on the new installer.
