Hi All,

Can I please introduce into the tree sys-kernel/module-rebuild.
This tracks linux-mod installed kernel modules, and also gives you the
ability to remove/add/toggle the list of modules to rebuild.

Basically.. following a kernel upgrade running: module-update rebuild,
will install all modules installed via portage.

If you experience any problems, please file a bug at bugzilla. Likewise,
please file a bug and assign it to johnm@gentoo.org if you have any
ideas about the tool.

On a side-note, give it an hour before you sync and merge this thing :)

Regards,
John

Thanks!

I'm installing and playing with it as I type.  The code looks a lot
cleaner than the code I had plagiarized from revdep-rebuild to do the
same thing.

Paul

I personally think that the following is sufficient:

# emerge -pv $(equery b /lib/modules | sed -e 's:^:>=:' )

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild   R   ] media-sound/alsa-driver-1.0.9_rc2  -debug -doc +oss -pcmcia 0 kB 
[ebuild   R   ] media-video/nvidia-kernel-1.0.7174  -pcmcia 0 kB 
[ebuild   R   ] sys-fs/cdfs-2.6.3a  0 kB [1] 

Total size of downloads: 0 kB
Portage overlays:
 [1] /usr/portage-chutz
 [2] /usr/portage-maildir

I am not trying to shoot down your idea, but you could probably use
something similar to automatically generate the list of packages to
rebuild if the database is empty?

I thought about this, but not wanting to depend on gentoolkit makes
using equery for example a little awkward.
This, I'm sure isn't fully feature-rich yet - and something like this
will be the next addition to go in.

I've uploaded here the script i use here to rebuild my modules:
http://tdegreni.free.fr/gentoo/emodules

It's in bash too, and i think there are some functions that could
help for implementing the feature you are talking about:
 - get_kernel_KV() gives the $KV value corresponding to a kernel
sources tree.
 - get_cpv_KV() gives the $KV value from the saved environment of
an installed package.
 - list_cpv_to_build() gives the lists of packages providing
modules that were not last built using the right $KV.

It doesn't use equery neither, but rather direct access to the 
${ROOT}var/db/pkg.

Feel free to copy/past whatever you find useful (there's probably
no legal header, but it's gpl in my mind).
