See  http://wiki.sugarlabs.org/go/LiveOS_image for some information on the
storage options.
Also http://fedoraproject.org/wiki/Livecd-iso-to-disk.pod has more help
information for the script.

With VirtualBox3.2.6 in a Lynx 64-bit host and a Fedora 32-bit guest, I
tested the Fedora-14 soas-i386-20100613.15.iso (no longer available, but
should be similar to the builds at
http://alt.fedoraproject.org/pub/alt/nightly-composes/soas/) using this
installation script,

/LiveOS/livecd-iso-to-disk --overlay-size-mb 1000 --home-size-mb 200
--delete-home --unencrypted-home /dev/live /dev/sda1

The command,

 dmsetup status

 before and after

yum install dkms gcc

yielded these results: 21376/2048000 and 868152/2048000 (512-byte segments)

So it looks like at least 425 MiBytes of overlay is required for that
installation.

then after

./VboxLinuxAdditions-x86.run

dmsetup status showed 928872/204800 or 454 MiBytes of the overlay consumed.
