- Core Upgrade (hybrid and headless) works
- MD Upgrade works (at least for me), ran it yesterday and it finished within 8 hours....... could be worse! ;-)
Only one tiny thing is missing, you need to set permissons for initrd.img and vmlinuz for every MD!
This was the reason for my test yesterday!
No permission, no MD boot! ...
chmod +r /usr/pluto/diskless/<number>/initrd.img
chmod +r /usr/pluto/diskless/<number>/vmlinuz
chmod +r /usr/pluto/diskless/boot/initrd.img
chmod +r /usr/pluto/diskless/boot/vmlinuz
