 Frequently Asked Questions
 Does ASL install the atomic repository?
No. ASL does not install, remove, configure, or use the free unsupported atomic rpm repository.

 Will this disable any of my other repositories?
No, this installation will not disable any other repositories.
 Are these packages supported?
No. The atomic repository RPMs are not supported, and are provided AS IS. Any and all express or implied warranties, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose are disclaimed.
If you require supported packages, please use the Nucleus repository.
 Do you provide supported packages from this repository?
We do not support packages in the atomic repository. If you require support, please use the Nucleus RPM repository. Please see that page to purchase a license, and for instructions on using the Nucleus repository.
All RPMS in the atomic repository are unsupported. So if you require support, you will want to use the software packages from the Nucleus repository, and not from the atomic repository.
