What version of Debian live-boot are you using? If I drop back to 2.0~a16 using multiple overlays seems to work as the documentation states. When I upgrade to 3.0~a25 is when I see problems with errors when there are multiple overlays. Thanks!

In the lernstick[1] distribution we include so many software packages that the resulting squashfs would grow larger than 4 GB, which makes genisofs fail. To work around the 4 GB limitation we changed the calls to mksquashfs in /usr/share/live/build/scripts/build/lb_binary_rootfs to: Chroot chroot "mksquashfs chroot filesystem1.squashfs -e usr ${MKSQUASHFS_OPTIONS}" Chroot chroot "mksquashfs chroot filesystem2.squashfs -wildcards -e !(usr) ${MKSQUASHFS_OPTIONS}" This change puts the directory "/usr/" into its own squashfs file which fits quite nicely. When booting the system, both squashfs files are picked up and merged with aufs. I know, I know... workarounds are bad, stupid, bad for the environment, yadda-yadda, but it works great for our purposes. Feel free to improve and generalize our workaround.
