usefulness of mandriva-patches in kernel, or just new 2.614. kernel from source?
Hi, Is the patching of the kernel by Mandriva necessary?
(I mean for good functionning of the OS with mandriva tools or scripts or anything else) I may find some times to compile my first kernel. I have a 2.6.14 source from a magazine. I was going to add it alongside Mandy 10.2's kernel. In other words, should I look for a 2.6.14 mandriva patched source kernel (if this is available), or can I just upgrade to any 2.6.14 or above, without worrying too much about these mandriva patches. I know I could urpmi a new kernel, http://wwwnew.mandriva.com/en/security/kernelupdate but at the end of the day I want to see if I can do it from the source I have, or another source, not from a rpm). I have seen occasional rambling about mdk patching of the kernel breaking things. I really have no experience to say that it does. PS: This will be my first kernel compilation; I have plenty of links and readings to help me through, so this should be all right. |
The one thing I can think of that will break is supermount. Look in your /etc/fstab file and if you have supermount on the lines with /dev/cdrom or /dev/fd0 then your kernel is patched with supermount.
You can manually patch your kernel if you want to keep supermount or you can leave out supermount and change you /etc/fstab file so you manually mount your cdrom or floppy http://sourceforge.net/projects/supermount-ng <edit> Be sure you use the config file located in the /boot directory when you build your new kernel. That way you know you are starting from a "known good" config file. cd /usr/src/linux MYKERNEL="`uname -r`"; cp /boot/config-$MYKERNEL .config make oldconfig |

Thanks very much for these comprehensive answers.
I do use supermount. I will try with a vanilla kernel, and patch it for supermount. Quote:
I hope the 2.6.14 [edit 2.6.15 does this is the milestone] now makes smartmontools work with sata drive (I read somewhere about these kind of improvements). Anyway, this is the curiosity factor first :) The day I manage to get this to work, and I notice some incompatibilities, I will post back here. |

Yeah I asked on the cooker mailing list because I was confused about how it all worked:
