Doc Type:	Bug Fix
Doc Text:	* When starting an inspection of what collections are already enabled, a wrong variable was taken as a source of this information. In a specific case, when users ran a shell in an scl_enabled environment, and tried to enable an already-enabled collection, then the collection was enabled twice. This could have caused problems if the enable scriptlets were not prepared for something like this, and might have destroyed some parts of the original environment. This update accepts the correct variable as a source of information about the already-enabled collections, and the collections are no longer enabled multiple times.

Description Jan Zeleny 2013-04-23 09:46:40 EDT

+++ This bug was initially created as a clone of Bug #955668 +++

When running scl enable <collection> bash, a variable $X_SCLS should be filled with a list of collections that are enabled. When calling scl enable for the second time, content of $x_scls is read instead of $X_SCLS. In case of enabling the same collection again, it would lead to running collection's enable scriptlet twice.

In some specific cases, this can lead to malformed environment, as one of the basic assumptions of scl-utils is that once collection is enabled, it won't be enabled for the second time.
