livecd-rootfs/live-build/ubuntu-desktop-next/hooks/00-uid-gid-fix.chroot_early
Sebastien Bacher 5fa4811051 * live-build/ubuntu-core/hooks/00-uid-gid-fix.chroot_early: 
- copy touch hacks to create needed userdirs (lightdm & usermetrics),
    the users are added by the script and not the usual postinst so their
    uderdirs are not created as they should
