Hi Jerome, thanks for the insights :-)

So what is the combined size of all "programs which have settings
or high scores" which the user would like to be updated? Remember
that high scores in ramdisk are lost at reboot anyway and it is
possible that games just continue without error when they fail to
write to their highscore file.

> running the entire OS in RAM has some advantages.

That depends. As the combined uncompressed size of ALL packages
is more than 1 GB, many computers of DOS fans would be excluded
from being able to run a Live CD with more than 1 GB RAMDISK.

Also, even in Linux it is very uncommon to install uncompressed
source trees of large numbers of packages. People are more likely
to only install a few source trees while recompiling few packages.
In particular for a Live CD, I see no need to uncompress any of
the source trees at boot. As long as the sources are provided in
the compressed packages on the read-only part of the CD.

As far as I understand, one would still need more than 682 MB
of ramdisk space for a Live CD in that case? How much would
that go down if only packages which have to write to their
install directory get installed to ramdisk? And how big would
the 3 largest packages in that ramdisk be? Which 3 packages?

Would it be, for example, possible to make a Live CD which
runs on PC with 500 MB RAM, which could be used as 64 MB
for the apps, a few dozen MB for caches and the rest for
a large ramdisk for only those apps which need writeable
install directories, possibly excluding a few large ones?

For a stretch goal, how about 250 MB RAM? I think Win9x PC
which could boot from CD even had less than 100 MB and they
would have the advantage to have DOS game compatible sound.

Thanks :-) Eric
