RC_WHITELIST prevents a lot of services from being started on thin/fat clients
In the Ubuntu/
On the other hand, Debian/
For Ubuntu, where those variables are defined, the 000-init-whitelist plugin calls update-rc.d and prevents those services from starting on boot. A lot of those services are significant, for example cups (for printer sharing), ondemand (so that thin client CPUs don't overheat), sendsigs (for proper shutdown), binfmt-support (if wine or java apps are installed on the chroot), openbsd-inetd (if ident2 is installed on the chroot for squid), etc etc, see attached file.
Is there any reason for those white lists to be defined? Can we comment them out like Debian does?
