Bug Description
On Bionic Ubuntu Desktop booting to a live session is slow. It takes roughly 2 min on my test machine to boot from the "Try or Install Ubuntu" boot menu to a usable session.
It also takes 1 minute to logout and 17s to log in again.

Hi,
The following bug has been reported in debian:
===
Dear Maintainer,
fontconfig now requires nano second mtime precision on files in order to
validate their freshness. squashfs does not seem to support nano second
mtime precision causing any Desktop ISO's made with live-build to regenrate
the font cache at the desktop startup leading to a very slow time to desktop.
