 Posted: Sat Jul 10, 2004 11:26 pm Post subject: symlink not pointing to new kernel source |
 |
|
Hi guys,
This is my first time compiling my kernel other than apt-geting it once. I'm following the instructions in the handbook, and emerged gentoo-dev-sources (When I first installed gentoo I emerged gentoo-sources with the 2.4 kernel).
So now I'm doing a | Code: | | ls -l /usr/src/linux |
and it's still pointing at my old one. How do I find out what exactly the new kernel is called, does it have a -gentoo-r1 or something at the end?
Just don't want to make too many mistakes during my first time..
Thanx
Dswissmiss |

Check in the /usr/src folder, and you should see a folder titled something like gentoo-dev-sources or something. To point the symlink to the new source, | Code: | | ln -sf /usr/src/linux-2.67-gentoo-r9 /usr/src/linux |

Check what kernels you have.
If for instance you kernel is called linux-2.6.7-gentoo-r9, you just do a:
| Code: | cd /usr/src
rm linux
ln -sf linux-2.6.7-gentoo-r9 linux |
Edit:
Heh, I was too sloooow.

One more question: 
After doing | Code: | | make && make modules_install |
I need to copy the image over to /boot, but doing an | Code: | | cp arch/i386/boot/bzimage /boot/kernel-2.6.5-gentoo-r1 |
gives me | Code: | | cp: cannot stat `arch/i386/boot/bzimage': No such file or directory |
I probably didn't use the correct filename, where would I find that?
Thank you |

capital I in bzImage
tip: use tab completion, type bz(tab) and it will complete the filename for you |

Dammit...sorry guys, I got one more.
When I saved the kernel, it saved to /boot, but following the gentoo handbook I originally created a seperate boot partition. So now I have the 2.4 kernel in my seperate boot partition, and the 2.6 kernel in my regular one... Can I copy those over somehow? I can't even view both at the same time in Nautilus, cause when I open /boot, and then mount the /boot partition, it only shows the mounted one...Hope I'm still making sense.
Thanx again

Hmmm, never used Nautilus myself...
But if you did follow the gentoo handbook;
| Code: |
mount /boot
cp /usr/src/linux/<whatever> /boot/<a_name>
(cp /usr/src/linux/System.map /boot/System.map-2.6.7-gentoo-r9 for example)
|
Should work well enough, though I am hardly awake yet so it is hard to tell =)
To actually move something from /boot to /boot on another partition is impossible I think (am I wrong?), you'd need to mount one of the dirs elsewhere.
To simply do the mount /boot and then copy the files solves the problem though.

You should really only have one boot partition. That said, it should also never be automatically mounted on boot for security and protection reasons.
You need to make sure that you mount your '/boot' partition first before copying over the kernel and possibly config and system map files.
I'm a little lost as to why you have more then one /boot and can only view one at a time. You may need to elaborate a little more in order for us to help you. |

Well, the problem is that I have a /boot partition, as well as a /boot folder. The /boot partition is on /dev/hdb6 and the /boot folder is on /dev/hdb7 along with the rest of gentoo (the partitions have high numbers cause I'm trying out different distros). So now my problem is that I can't seem to copy the 2.6 kernel which is in the folder to the /boot partition. If I mount the partition I can't see the folder and vice versa.
Any Ideas...and how would I prevent this from happening next time?
Thanks again |

Simple: mount the /boot partition before you copy the new kernel.
Even so, you can remove the kernel you mistakenly put in that folder before you mount /boot, then mount and cd /usr/src/linux and recopy the kernel, but this time to the /boot partition...

Can't you just move the kernel from the folder to something like tmp first?
And then mount /boot and move it there?
Until you mount /boot it's only a folder with a symlink in it.

This is true. Hence the reason in my former post that I didn't understand how you said you had more then one boot folder. If your /boot parition is not actually mounted then megadonkey is right - it's just a folder with a symlink. Just make sure you actually mount your /boot partition before you copy anything to it and it should all work out fine. |

I did it with copying the contents to a temp folder, mounting /boot and moving it there. Can't beleive such a simple answer escaped my mind.
I really suck at this though, cause now I get this error when booting the comp:
Warning: Unable to open an initial console
Kernel Panic: No init found. Try passing init= option to kernel
I tried putting init=/linuxrc to the kernel line but still get the error.
maybe I've been messing with it too much to notice the obvious, so here's my grub.conf:
default 0
timeout 05
splashimage=(hd0,5)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.5
root (hd0,5)
kernel /kernel-2.6.5-gentoo-r1 root=/dev/hdb6 vga=795 init=/linuxrc ramdisk=8192 [/code]
and when it reads root=/dev/hdb7, I get an error saying that it cant mount root on hdb7 |

Which one is your root? hdb6 or hdb7?
Also make sure you have enabled support for your filesystem in the kernel as * and not as modules.
If you have compiled your kernel manually and not used genkernel I don't think you need init=/linuxrc or a ramdisk. Well I've never used it anyway.
But as I said, make sure you have the right root specified in your grub.conf and that you have support for your filesystem.

well, this is turning out to be a really bad experience. i got to the command prompt, but i could only startx as root. after updating nvidia, glx and doing xorgconfig i could still only use gnome as root, and now i can't even do that.
I'll probably figure it out eventually, but in any case, can anyone please tell me all the steps necessary to update a kernel? is it jus nvidia and glx that i have to update as well, or are there other things...i think alsa needs an update too.
Thanx |
