Yes, I know, but _how_ can I do it? :) In u-boot is very easy but in Linux I still haven't found a good way to do so. > Another way could be using a dedicated kernel module for the job - eg. > you compile the graphic support in the module and the when update is > needed only module can be replaced in the file system leaving kernel > intact (at least while kernel version does not change). This is not solve the problem, you still need a compilation stage. I wish avoiding it. And, on the other hand, you cannot load a kernel module since you don't mount a root filesystem which is very late during boot.
