New changelog entries:
* live-build/ubuntu-core/hooks/04-configure_network.chroot: use
'allow-hotplug' for the network config, not 'auto', to work around
systemd behavior that causes 'auto' to delay the rest of the boot when
DHCP is not available on the network.
* live-build/ubuntu-core/hooks/00-uid-gid-fix.chroot_early:
- port static uid/gid setup from ubuntu-touch
* live-build/ubuntu-core/hooks/15-pycompile-snappy.chroot:
- byte compile .pyc files for snappy
