Purpose
Questions and Answers
 When performing "uptrack-upgrade" the latest patches will be stored in the memory or in local disk, for example, if the update is 100 MB in size, will the kernel allocate 200 MB from RAM? and will it hold the memory till next reboot?
 While allocating memory for the latest libraries which was pushed as part of "uptrack-upgrade" command to RAM, will the kernel discard the old libraries from RAM to free the space occupied by it or both old and new libraries will exist in RAM?
 How much memory would require to install any new ksplice patch? if anyone planning to use this ksplice to his environment for the long term without a reboot. Will more memory will be utilized by ksplice patches if it used for the long term?
