Description: 

Installation profiles provided by Drupal core are now contained in:

/core/profiles

Contributed and custom installation profiles can now be located in any of the following locations:

/sites/all/profiles
/sites/[site]/profiles
/profiles

Previously, installation profiles provided by Drupal core were mixed into a single /profiles directory, which also served contributed and custom installation profiles. The lack of separation made updating/upgrading Drupal core harder.

The new locations not only provide a proper separation between Drupal core installation profiles and custom/contributed installation profiles, but also allow to limit installation profiles to a certain site/domain (if known upfront before installation).

Details: 

Since profiles are not well documented (not even mentioned in INSTALL.txt) and a file /profiles/README.txt exists, we could use it to elaborate on the profiles functionality there first, and later refactor it into INSTALL.txt or other places if necessary.

Progress: 
/profiles/README.txt file needs review: http://drupal.org/node/1539940
