I would like to understand how Mint (per se, any other Desktop Environment) work in case of multiple kernels installed in a system. I recently upgraded my Kernel from 3.2 to 3.8 and GRUB presents both the kernels and could select either of the kernel while booting as desired.
Both kernels work on the same root and home partitions. I believe when a kernel is installed it generates an image which will store all the configurations in terms of applications installed,etc.
I will be grateful if someone can take the pains to explain / point to material on how desktop environment interfaces with kernel. Looks like desktop environment is coupled with kernle loosely enough to talk to mutilple kernels. (Non-concurrently)
I have also upgraded my KDE to 4.10 and kernel to 3.8. Also, how does Mint update manager handle and upgrade only the relevant package since I have deviated from initial installation.
Thanks for your time.
