/tmp has been traditionally cleaned up during (early) boot in Debian.
This has always been the case (alredy under sysvinit)
Services which run during early boot need to make sure to explicitly
specify the orderings and dependencies.
In this case console-setup just needs to add the proper After= directive.
Why this hasn't happened yet is unclear to me. Please poke the
console-setup maintainer about this.
