Hello Geoffroy,

OSCAR calls si_prepareclient with the --server and --norsyncd options. This is fine with the default version of SIS, but newer ones will issue an error, saying that these two options are mutually exclusive. As far as I am concerned, no change is necessary in OSCAR until systemimager is updated in CentOS (or is the package installed by OSCAR?). > I suspect a module to not be loaded automatically.

No, there is no /etc/modules either on the master or the image. >> You are right, it is i think good to double check that point and >> make sure you try with a proper UYOK configuration.
