Reposted from gentoo-server:


Gentoo is moving to 2004.1, 2004.2, 2004.3 style releases. This gives a working baseline for the stable trees that need to be supported.

A new profile can be used to show which baseline the machine is following. For example, "2004.3-x86". This profile (or USE keyword), as "x86" and "~x86" already do, sets the version of the packages that are loaded into the system.

The life-cycle of, for example, 2004.3-x86, would be:

  .
  .
  Current x86 profile copied to 2004.2-x86
  2004.3 baseline released.
  x86 and ~x86 operate as they do now.
  .
  . <time passes>
  .
  Current x86 profile copied to 2004.3-x86
  2004.4 baseline released.
  x86 and ~x86 operate as they do now.
  .
  .

Over time, the older profiles can be tweaked to include security updates and minor version updates. This information will allow repoman to go through and cull out the distfiles and ebuilds that are no longer required by an aggregate of all profiles in use.

Over time, the baseline profiles should merge to some degree as say, 2004.1 and 2004.2 point to the same ebuilds for final releases of particular package versions. This will further diminish the amount of storage and processing that is required to support old package versions.
