I assume it would be feasible to record the sequence of disk accesses
during a normal boot from CD/DVD and ensure that the required blocks
are in the ISO in linear disk-reading order, which should speed boot
time from optical media.
I guess that means booting the ISO image during the build in something
virtual, with a magic kernel option to make it spew all the disk
access addresses, then reorder the ISO accordingly.
Does anyone know if this is already done in live-build, or if any
other ISO build systems do this?
