 Posted: Wed Feb 15, 2006 1:49 am Post subject: How do you keep portage from removing old kernel modules? |
 |
|
| I want to be able to use several kernels and there are some modules built outside the kernel like ibm_apci and fglrx that portage will uninstall when I upgrade the kernel. That is, I can only have those modules built for one of my kernels and if I want to use another kernel, I can't use the modules. Is there any way to keep portage from uninstalling modules when you recompile 3rd party modules against a new kernel? |

do you have
AUTOCLEAN="yes"
in /etc/make.conf??
You wouldn't want that disabled and, I believe, portage will not clean out unless you explicitly say so. |

I thought that was just for the crap in, say, /var/tmp/portage? I'll give it a shot. |

| No, autoclean is definitely for cleaning out old versions of pkgs whenever you upgrade. Cleaning out /var/tmp/portage must be done manually, afaik. There is no way to make portage automagically clean out /var. |

Alternatively, I don't see why you can't do this:
#AUTOCLEAN="no" emerge foo
Since you can pass such vars as ACCEPT_KEYWORDS and USE at the command line when emerging specific pkgs, I think you should give this a shot. That way, your system will always be cleaned after updating, but keep your kernel modules a manual updating endeavor, and prevent them on a per-instance basis from being cleaned. |

Well I do that anyways. I just don't want portage to get rid of all my old modules that are already installed in /lib/modules. I want to be able to have multiple ibm_acpi modules, for example, one for each kernel. Portage always seems to uninstall the ones belonging to other kernels. |

You could add /lib/modules to CONFIG_PROTECT in make.conf I guess.

that's not true. portage never deletes any modules from under /lib/modules.
that said:
you do have to remerge ati-drivers and whatever else every time you install a new kernel (or modify the configuration of an existing one)
you do have to keep /usr/src/linux (the symlink) up-to-date
you should probably consider cleaning out /lib/modules from time to time

1) set the linux link to point to the kernel you are building in /usr/src/
2) build and install the kernel and modules
3) emerge all the third party kernel modules you want that kernel to support
5) start at step 1 again until you finish building and installing all of your kernels
