Re: Using lm-sensors

[Ross Boylan <RossBoylan@stanfordalumni.org>]

Thanks for the info.  So is the relation between lm-sensors and 
lm-sensors-source that the latter provides drivers used by the former (sort 
of like alsa, where you need to build the driver, but the utilities can be 
obtained by binary package)?

Or is lm-sensors simply a packaging artifact that doesn't work, and that I 
should remove before attempting to install the package I make from lm-source?

Thanks for the tip on disabling i2c in the kernel--sounds as if it will 
save a lot of confusion.

My current thinking about the proper steps:
apt-get remove lm-sensors
apt-get install lm-sensors-source i2c-source
untar, establish links and environment variables to get those two modules 
where I actually
                 have my kernel  modules
make-kpkg clean
disable i2c in kernel configuration
make-kpkg --revision=rb.2 build_image  #not sure this or next target is right
make-kpkg build_modules  # I'm not in Debian right now to check
                                       # but you get the idea
dpkg -i <kernel.deb>
dpkg -i <modules.deb>  # with appropriate directory renaming since I 
already built this gen kernel.

Hmm, I don't think we have the usability issues quite licked.
