Can not find a appropriate forum to post this question. So post it here.
Basically in regarding to the licensing of SUSE Linux Enterprise Server, my understanding is that this software is free to use so long the user does not want to get the updates and support. However, if the user wants to get patches and support from Novell, then the user must purchase a subscription and support license.
The reason I believe the SLES is free in nature is because it is GNU licensing based.
Please correct me if I am wrong.
