 Install on Vanilla openSUSE/SuSE SLES
 =====================================
 
-Our installer profiles (`<https://github.com/rockstor/rockstor-installer>`_), and consequently our pre-built installers, deviate only a little from openSUSE’s JeOS appliance profiles.
-As a result, it is possible to manually configure a Vanilla openSUSE/SuSE SLES based install to then install Rockstor's rpm.

     **For advanced users only**
 
     This install method is predominantly for developers or advanced users and will likely require additional maintenance.
-    It may also serve as an option where a SLES base is required. Please note our undesirable disabling of apparmor.
-    We hope to resolve this partial failure in due time.

-The base OS version is assumed to be already found within our Rockstor 4 `Installer Recipes <https://github.com/rockstor/rockstor-installer>`_, and in the case of SLES, to be at least version 15.4--when the upstream binary compatibility between openSUSE Leap & SuSE SLES matured.
