Removing modules of running kernels

[elsa]

Hi,

 

I know at least some distributions don't remove modules of currently running kernels. Even when upgrading kernels and modules. Also, armbian has files like /etc/apt/apt.conf.d/01autoremove etc, which look like they're meant to accomplish the same (protect selected kernel modules from removal), but have in fact no effect (by default).

 

How can I prevent removal of files on upgrade (specifically, kernel modules)?

 

That is, enable the /etc/apt/apt.conf.d/01autoremove and related things to have an effect, or set some other option to do something similar.

 

Actually, I would also prefer to keep a few previous kernels and support files (the files in /boot). Just what some other distributions do by default.

 

thanks
