Title:
LiveCD layout optimisation
_
Personally I don't know how to go about looking for the root cause of
this 180 MB increase, or I would.
On ext3 the new disc did not do this. It must be something related to
ext4. This is all I know.
Thanks for your review, Martin. :)

Personally I think that six seconds won at livefs boot time (at a boot
time of two minutes) isn't enough of an advantage to sacrifice 180 MB of
installed size.

As I just saw and posted about on ubuntu-devel-discuss [1], using the
new squashfs layout file for a CD made Ubuntu's hard-disk install size
180 MB bigger on ext4. I presume it's due to extent allocation breaking
due to the pattern of file copies.
The status of this bug now depends on whether Live
This sort file makes ISOLINUX bring up the screen with boot options in
less than 2 seconds after first displaying ISOLINUX, by putting every
file read by ISOLINUX in sequence right at the start of the disc.

The boot time AFTER the mksquashfs optimisation is 1 minute 59.09
seconds.
Of note: I had to work around bug 512172 in pybootchartgui to generate
the images. And this is on the Jolteon defined above.

Now doing tests with the bootchart package, which was added to Maverick
dailies on 2010-06-10. Thanks cjwatson!
The boot time BEFORE the mksquashfs optimisation is 2 minutes 05.33
seconds.

I did preliminary results for this bug with a stopwatch. I'll explain my
methodology in this post and put my results in the next one.

that appears when boot starts, and the Lucid orange-purple background
