[Bug 1749546] Re: Booting a live session is slow

[Will Cooke]

Thanks to ali1234 this was tracked down to font-config rebuilding the
cache at the start of the live session.  Something changed in the way
fontconfig validates the caches and so they are being rebuilt at the
start of the live session.

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.
