 Posted: Wed Jul 14, 2004 7:47 pm Post subject: Too many gentoo-dev-sources 2.6.7 releases! |
 |
|
Is it just me or has there been an entire slew of "stable" kernel releases in the gentoo-dev-sources arena?
It feels like I've been rebuilding my kernel every day or two for the last couple of weeks.
I've even got the whole process down to 3 lines!
I saw a comment somewhere a while back saying that "a load of the patches had been removed ... feel free to raise bugs ..."(paraphrasing), so I assume this is just the patches going back in, but it's making a mockery of my uptimes, anyone else feel this is a little out of hand for the "stable" line of kernels? |

Just yesterday I added
| Code: | | >=sys-kernel/gentoo-dev-sources-2.6.7-r9 |
to /etc/portage/package.mask. I'm going to stay with r8 for a little while.
Cheers.

I am still learning about how to make multiple kernels, so how do you add a new updated kernel so easily? Also, are you upgrading or actually having multiple kernels on your computer?

keep them under different filenames in /boot and edit your bootloader so you can pick which one to boot

I totally agree, these gentoo-dev-source revisions are getting out of hand, kernel 2.6.7 was released June 16th, and we already have r11, thats a new revision every third day!
I did the same thing today as malone and masked everything above r8. |

I have been doing some research on how to install multiple kernels, but the faq document does not make any sense to me. If I already have a kernel up and running, what do I need to do to install another kernel on the same partition without overwriting my current one?

The lastest fixes is only SPARC related.
You dont need to upgrade or `emerge sync` every day..
The Gentoo kernel team is really fast at fixing bugs and thats a good thing.

Once the kernel has been loaded, you can do whatever you want to the bzImage in your /boot, it will overwrite the existing one, but the changes will not take effect until you reboot. If you wish to have multiple kernels in your /boot, to select from when you boot, then just name it something else. I usually rename the bzImage to the name of the kernel, i.e., gentoo-dev-sources-2.6.7-r10 or wvr, and then edit your bootloader accordingly. |

Okay, that makes sense. So all I would have to do is #make menuconfig to compile the kernel, save it as something different, and then add the path to the new kernel in grub?

There is a lot easier way to install kernels without editing the grub config every time.
| Code: |
cd /usr/src/linux
make menuconfig # edit the config to your needs
make
make modules && make modules_install
mount /boot/
make install # this will make a symlink called vmlinuz in your boot partition
|
the vmlinuz symlink points to the kernel you just compiled, if there is a vmlinuz symlink in /boot already, then it will rename it to vmlinuz.old
`make install` will also copy the current .config and System.map to /boot/ - if old symlinks exsist, it will rename them to .config.old and System.map.old
just make 2 entry's in grub.conf
one for vmlinuz and one for vmlinuz.old.
If your newly compiled kernel fails to boot, then you will always have the old one (vmlinuz.old)

Awesome. Thanks GentooBox. That answers my question.

| Anybody know where we find out about what is changed in each revision? What about the features of all the other kernels? |

To see a short description of a kernel in gentoo portage:
| Code: |
emerge -s gentoo-dev-sources
|
to see a short changelog:
| Code: |
emerge -l gentoo-dev-sources
|
or check at http://www.gentoo-portage.com/
You can get the vanilia-sources (the normal linux kernel) changelog at http://kernel.org
If you want to know more about some kernel in gentoo portage, then you have to use google.com or search at this forum.
