No python please, it has the same poor boot

I use a simple test script for this kind of check, see

One thing

Sorry for the 4th post in a row, but I added a script that uses
AdvanceCOMP to recompress the .gz files that aren't man pages, and I
had to share my findings.
AdvanceCOMP? | ISO size (B) | Install (KiB)
No | 711,032,832 | 2,474,660
Yes |
Apologies for the previous attachment, it didn't have the addition for
man-page symbolic links.
I attach the proper one this time.

[ compression related discussion removed ]
So maybe we can save some MB with better compression, but we can save more by
not including files at all. Of course this requires inspection of the packages
included on the liveCD. In the past we did identify some issues and did add
some diagnostics

While I've tried to reduce the quotes and quote nesting as much as I
could, this message is still long. It is still important to read, when
you have time.

That's not strange, that's just entropic packing principles. You've got
a bunch of assumptions th

Hey :)
Thanks for the interest in this optimisation! Unfortunately I wasn't
pushy enough in my thread from May-June and it wasn't included in the
Maverick LiveCD. A pending question is what to do to include the
recompressed files into the archive's packages [1].

In May, Louis Simard proposed rencoding PNG files and SVG files to
reduce their size [1]. I note that we can save further space by:
1) Using advdef on the png files in addition to optipng. This is what
optimizegraphics does, and this shrinks the pngs on the Maverick RC
liveCD from about 100.1MB to
19 matches
