Comment 3 for bug 2028213

I guess at some point in the construction of the minimal.standard.live layer, the /var/lib/snapd/seed/snaps directory got deleted and recreated. The way overlayfs represents this is not very helpful to the construction of minimal overlay squashfses :(

It seems I sort of predicted this situation in my comment here https://git.launchpad.net/livecd-rootfs/tree/live-build/lb_chroot_layered#n135

(on my list of things-i-want-to-look-at-but-have-never-got-around-to is seeing if rsyncing the layer into a fresh overlay is a better way of implementing reduce_pass_size)
