 Posted: Sat Feb 09, 2013 12:21 pm Post subject: [SOLVED] About kernel upgrade |
 |
|
Hello,
I just installed Funtoo with kernel vanilla 3.7.5. When I run emerge -uDN --with-bdeps=y @world, it looks like it emerged version 3.7.6 of the kernel. However I formerly (with another Gentoo installation) had troubles with kernel upgrade. It literally messed up my kernel configuration and I had to use genkernel to get a working system as soon as possible.
I don't want to make the same mistake twice. But I also don't want to spend too much time reconfiguring the kernel each time a new release is available.
Is it a good idea to stay a long time with kernel 3.7.5 (adding >sys-kernel/vanilla-sources-3.7.5 in package.mask)?
Or should I port my configuration from one kernel to another? What precautions to be taken? I suppose just copying .config from linux-3.7.5 to linux-3.7.6 is not a good idea.
Thanks for your help.

Just copy your config and run
Sometimes it will prompt you to make choices, usually N is default and they are not needed (make sure to not just blast through these hitting enter just in case).
Also finish off with "make nconfig" or similar to just have a quick look and check things are set correctly, if you feel the need to.
Edit: Just to point out, this is all covered in the documentation: http://www.gentoo.org/doc/en/kernel-upgrade.xml // http://www.gentoo.org/doc/fr/kernel-upgrade.xml |

| Code: | cp /usr/src/linux_old/.config /usr/src/linux_new/
cd /usr/src/linux_new/
make oldconfig
make && make modules_install |
move the compiled kernel into place and update bootloader (if applicable). Lilo for instance.
o and update the linux symlink if this has not yet been done automatically. |
