ns2 ~ # emerge –sync
ns2 ~ # emerge –update –deep -p world
to check?
ns2 ~ # emerge –update –deep world

Eg., copy old .config to new kernel and run
ns2 linux # make oldconfig
compile kernel, set grub
if using nvidia for graphic must re-compile nvidia modules else X not startup.
Eg., run “module-rebuild rebuild”. Need sys-kernel/module-rebuild or
ns2 ~ # emerge ndivia-drivers
ns2 ~ # ldmod | grep nvidia && rmmod nvidia
ns2 ~ # modprobe nvidia
ns2 ~ # update-modules
