Question about RHN usage: We have several hundred RH Linux systems registered in the RHN facility but use it infrequently since we are only required to install a few patches within a year. The problem we have is that our systems get automatically unregistered by RHN after 30 days of no activity and then we have to enter them all over again when we have a new required patch to install. How can we extend the 30 day inactivity period or make it so that there is no expiration for our registered systems? Thanks in advance for help provided.
