 |
|
Hi all,
I'm just trying to grab a grasp of the Gentoo updating process.. I am not using Genkernel and I was wondering If I need to recompile the newer version kernel in order to make a full system ugrade, cause when I did: | Code: | | emerge --sync, emerge --update --deep --with-bdeps=y --newuse world |
I ended up with a broken system and the compilation process didn't go through.
Could someone post the proper steps to upgrade/update a Gentoo system?
Thanks! |

That doesn't explain the steps.. Basically my question is. Do I have to upgrade the Kernel each time I'm performing a full system update in order to avoid any issues? |

I dont want to mess too much with full system upgrades. I usually just want to update packages due to security issues.. Is there any way to just update the security needed packages and not all the system? |

No, you don't have to upgrade and recompile your kernel each time on a full update. Occasionally there may be a package in your updates that requires a certain kernel option, and you will get a message about that.
Also, if you have an update failure, it is very helpful to post the exact errors you get.

If you have a recent enough portage, then: emerge -a @security
But, Gentoo is a rolling release distro. So it is recommended to do a full upgrade regularly (at least once a month). The longer you wait, the more likely it will be you get problems on updating your system.

Does this mean that I have to upgrade my Kernel every month too? |

| Quote: | 2. Why upgrade the kernel?
Generally, upgrading from one minor kernel release to the next won't bring any major differences. There are several reasons to upgrade the kernel. One is to take advantage of a specific new feature or driver; another is to be protected against a security vulnerability, or just to maintain an up-to-date and healthy system.
Even if you choose not to update to every new kernel revision, it is recommended that you at least upgrade from time to time. It is strongly recommended that you immediately upgrade to a new kernel if that new release solves a security problem. Good idea, but Gentoo/Linux is about choices so you upgrade when you want to... |

So every Month, PAIN.. |

No, not necessarily. |
Is it possible to exclude system updates that are related to kernel upgrades? |

no, but you can froze your current kernel version in world so portage will always keep it, you will get other kernel update, but won't have to care about them until you want change it
and before you ask it's easy, instead of
emerge gentoo-sources
you use
emerge gentoo-sources-versionyouwantkeep |

Gentian, I update mine every week. Small updates are easier to handle and quicker to execute. I set the number of processors in make.conf to one less than I have and usually surf the web while the system is updating in the background.
This doesn't always work. This weekend I had 115 updates! The dev's must have marked an awful lot of versions as stable.
anb.clarke, are you erasing your posts after entering them? They are all blank. |

Or perhaps he has a hidden agenda.

Ok.. Is this the proper way of upgrading/updating things? | Code: | eselect kernel list
eselect kernel set
cp /usr/src/linux-$(uname -r)/.config /usr/src/linux/
cd /usr/src/linux
make oldconfig
make modules_prepare
module-rebuild populate
module-rebuild rebuild
make && make modules_install
emerge --update --deep --with-bdeps=y --newuse world |

You should build new kernels once in a while, but you do not need to update it every release. What I've found recently is that it's mostly
- closed source drivers
- udev (that add new features that require the kernel to track)
- and other special tools tied to versions of the kernel, which is not unlike the closed source driver issue.
that can force a particular kernel to be used. My server which I try to not build kernels for is still running an ancient 2.6.38 but still running latest versions of stable portage packages, thankfully there haven't been udev enhancements that require newer kernel versions.
I should update that kernel anyway - mostly for security fixes.
And agreed (mostly from past experience), update your machines semi frequently - the longer between updates, the more likely you'll run into strange dependency issues. Then again, the more USE flags in packages.use also can cause this too.
Note: You should reboot your systems once in a while, not wanting to reboot is not an excuse for not wanting to build new kernels. Picking up security changes should be the prime reason for building kernels, and it's up to the user to judge this...

You also have to manually update /boot/grub/grub.conf if you do it that way. I haven't done it the "roll your own" way for a long long time. I find genkernel to be a most useful tool. Using the menuconfig option you can customize and trim to your hearts content. You can start with pappy's seeds or take the install disk configuration and pare it down.
Whether with genkernel or roll your own, the option to create /proc/config.gz that I referred to upthread is enable from menuconfig by selecting "General Setup" and selecting "Kernel .config support". Whether or not you use my script, /proc/config.gz can be very useful in debugging and posting to this forum. |
