kmod packaging question

kmod packaging question

[Gary Thomas]

I'm having some issues with the 'kmod' package.  In particular,
the package claims:
   commit b4bc0a7f1b90a51e26d6ab74d964ff81cfe05904
   Author: Khem Raj <raj.khem@gmail.com>
   Date:   Tue Jan 31 00:34:01 2012 -0800

     kmod: Add recipes

     kmod is replacement for module-init-tools

     (From OE-Core rev: 716606f5446534e48b45fcc017e8bbdfe7f15e26)

     Signed-off-by: Khem Raj <raj.khem@gmail.com>
     Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

But is is really a "replacement"?  I know that there is a provides
which makes the build happy, but unless you explicitly install the
kmod package into your image, you don't end up with all of the module
tools.  The main missing piece is 'depmod' - the rest seem to come
from busybox, not kmod.

I ran into this when trying to run 'opkg upgrade' which sucked in
some new kernel modules and found that 'depmod' was not installed.

Did I miss something?

n.b. this was tested using Poky/Yocto 0fc8317c6385eb1ed69ca4522ee6424c456dbb92
which is a few days old.  I've not checked the very latest master (yet).

Nope, it was a good catch, I will investigate the size increase for 
adding depmod into busybox.

Seems it adds 2240 bytes to the size of the busybox binary, that's far 
better than 675K that kmod would bring in.  I will get the patch up shortly.
