How does UCS releases relate to Debian versions?

I could not determine from any external sourcing how UCS releases relate to known Debian versions. I gathered that 3.0 related to/was derived from Squeeze (Debian 6.0) from an article, but could find nothing about 3.2 or any useful info about this findable.

This related to the question of packaging. I noticed the UCS packaging guide for 3.2 still refers to rather old ways of creating and maintaining debian packages, when using debhelper, especially dh >= 8, makes it so very much simpler to do. This made me consider that 3.2 might still be pre-wheezy.

from UCS 3.2 Release highlights:

[quote]- The underlying Debian base has been updated to version 6.0.8; this imparts numerous improvements and bug fixes.

  • The Linux kernel has been updated to 3.10.15.
    As you can see the kernel version is newer than the current one in Wheezy. I dont know for sure if other components or packages are handled comparable.

AFAIK UCS 4 is planned to based on Wheezy.
