Purpose
Questions and Answers
 1. When performing uptrack-upgrade, are latest patches stored in memory or on-disk?
For updates with a collective size of 100Mb on-disk, say, will the kernel require 200Mb of memory for both old and new updates?
If so, will they remain resident in memory until next reboot?
 2. When running uptrack-update to apply latest patches to memory, does the kernel discard older copies of libraries, or do both old and new copies remain resident in memory?
 3. How much memory is required to install new Ksplice patches?
If planning to use Ksplice updates for an extended period without reboot, how much additional memory will be used by both old and new copies of libraries?
