One of the flags that I had with kernelmod-rebuild was a -S, --smart-rebuild flag which would only rebuild modules that were missing from /lib/modules. I just saw this on the gentoo-user list and it jogged my memory that module-rebuild had no such option. > The Gentoo newsletter mentioned the new module-rebuild script, > so I emerged it and ran it with the following results. > > # module-rebuild list > ** Packages which I will emerge are: > =media-libs/svgalib-1..21-r1 > =net-wireless/ieee80211-1.0.3-r2 > =net-wireless/ipw2100-1.1.2-r3 > > So I ran > > # module-rebuild rebuild > > and it seemed to rebuild the three packages in question. > > As a check, I then ran module-rebuild list again, and it > listed the same three modules as before.

my problem here is that module-rebuild is actually doing the right thing, since even though s module might exist for the actual kernel version in question, the kernel image itself may have totally changed vermagic or a various collection of other situations. It is imo always best to rebuild a module, whether the file exists or not. the only more accurate test would be to load the module, but this isn't an option since it introduces stability questions. unfortunately, I cannot foresee this working. Any suggestions/code welcome.
I haven't had a chance to do code yet, but even if I did, it would have to be an off by default, you pick up the pieces if you have significantly changed your kernel type of thing.
