Hi folks,
Several people have been asking what /sbin/weak-modules is/does,
mostly because it started script spewing the other day (sorry about
that!) on kernel updates.
weak-modules is part of some driver updates work we're doing at Red
Hat and also involves folks working on Fedora Extras "kmod" kernel
packaging (see the packaging list archives). Essentially, this and
other scripts are part of a system for allowing compatible kernel
modules to continue to work after a kernel update occurs -
weak-modules is the part that figures out which kernels are compatible
with a driver.
There's more information (and some out of date packages - look at
rawhide for the current latest stuff!) at
http://www.kerneldrivers.org/ and I will add documentation for those
who were looking for it and could not find any - I'm sorry that's not
been done yet.
I'm trying to work with the folks at SuSE/Novell to ultimately offer
kernel module package authors a standardized packaging process too
(over and above what we each do separately) - I'm going to start by
introducing a new macro in redhat-rpm-config along the lines agreed
between those of us who met up at OLS to discuss driver updates last
week. This is not aimed at undermining the work that's been done in
Extras - it's just an additional option.
If you would like more information, just drop me an email (I'm also
jcm@xxxxxxxxxx when wearing my work hat!) or reply to this one.
What exactly is the problem being solved here? I don't see any obvious
link to anything on kerneldrivers.org that describes what this stuff does.
I build lirc and ivtv modules each time a new kernel comes out, and I
have absolutely no problems doing that. Couldn't be any easier. Piece
of cake. I'm not sure what problem needs solving here. I just install
the new kernel and kernel-devel packages, run the script that builds a
corresponding lirc and ivtv kernel driver packages, pointing the build
at the right build directory, then install the driver packages and
reboot. Couldn't be simpler.
If someone really wants to make building kernel driver packages easier,
they can simply fix THE HORRIBLE UGLY STINKING CRAP code that
kernel-devel's %post script uses to hardlink the identical kernel source
files.
If I set out to do this specific task in the most grossly inefficient
manner possible, there's no way I could do it any better than the
existing mess. The brain-damaged script literally reads the entire
/usr/src/kernels, by forking thousands of mind-numbing child procs.
And, the more kernels you have installed, the slooower and
sloooooooooooooower everything takes.
Has anyone ever heard of this thing called an SHA1 hash?
Anybody?
Hello!!! McFly!!! Anybody home????
Anybody heard of being civil? If you have problems, file bug reports.
