All,

Working on the postinstall improvements I stumbled over update-modules
script which postponed postinstalls for all the kernel or kernel module
packages for first boot. However, after some investigations I saw that this
script is pretty much obsolete. So, this patchset will remove it from all
recipes and bbclasses it was referenced.

Here's why it's useless now:

update-modules was used mainly to create the /etc/modules.conf file, out of files
in /etc/modutils, and /etc/modules file from /etc/modules-load.d/*.conf files.
Then it just ran depmod -A.

* depmod can be run in the postinst/postrm on its own, no need to run through update-modules;
* /etc/modules.conf is not used anymore by modprobe. modprobe now looks in
  /etc/modprobe.d/ directory for *.conf files;
* /etc/modules was used by /etc/init.d/modutils.sh to automatically load
  modules at boot. However, I improved the script in order to also look into
  /etc/modules-load.d/ directory and load all the modules listed there that were not
  already loaded (in case /etc/modules existed);

I know this is a major change and will affect a lot of people. But, in order
to support RO rootfs and run all the postinstalls on host, this change was
kind of necessary. Note, though, that the update-modules recipe was not removed
yet. It will be removed eventually but, for now, I decided to leave it in place
in case some people are nostalgic and want to still use it for a while.

Feel free to review and comment on the change.

Thanks,
Laurentiu

I've merged these, I'll also take a patch to remove update-modules
itself.
