I’ve installed a prebuilt image onto am Honeycomb system and did some customisation - adding new packages etc. a few months ago. Now I’d like to upgrade to the lastest software, but without having to reinstall and reconfigure everything from scratch again.
Is there a recipe for this? For the whole user space it’s easy - a apt update && apt upgrade will do the trick. But kernel etc don’t get updated. So I downloaded the lastest prebuild image, used a loopback device to mount it, found an xspi_header.img and an ubuntu-core.img in it, copied both, unmounted the image, mounted the ubuntu_core image and got a Linux rootfs.
What do I need from this?
- /boot/*
- /extlinux/*
- /lib/modules/*
Anything else?
Best Regards
Frank.
