Thanks for flagging this up. I hadn't thought of that. I will fix it.

I will find them and uncomment them in the rootfile.

What is the best way to submit these updates. Just a v2 update for the patch 2/3 plus another patch for the rootfile update or should I do a v2 patch submission for the complete set of three patches from the original set together with an additional patch for the rootfile changes?

Regards,

Adolf.

What is the benefit of unloading the kernel modules?

Wouldn’t they automatically be reloaded once something triggers udev?

I tested installing the alsa addon on my production machine, which doesn't have any sound capability at all and I don't plan to install it. However, after installing the alsa addon I had the modules loaded and after uninstalling the alsa addon those alsa related kernel modules stayed there and would persist till a reboot was done for a core update for example.
It just seemed to me that unneeded kernel modules shouldn't stay loaded up just because an addon was installed for a test and then removed.

It seemed that things that installed modules should remove them when they are uninstalled.

Maybe the unloading should be moved to the uninstall.sh file rather than in the initscript. That might make more sense because then the addon has been completely (hopefully) removed.

Regards,
Adolf

[PATCH 1/3] alsa: Fix bug#13087 remove services entry

[Adolf Belka]

[-- Attachment #1: Type: text/plain, Size: 1205 bytes --]

- alsa has an initscript but it is not starting and stopping a traditional daemon service.
   The initscript loads some alsa modules and then restores the asound.state file
- This patch updates the PAK_VER number and removes the services entry and explicitly
   adds alsa in for the initscript installation.

[PATCH 2/3] alsa: Fixes Bug#13087 - adds module removal for stopping alsa.

[Adolf Belka]

[-- Attachment #1: Type: text/plain, Size: 1085 bytes --]

- Stopping alsa or uninstalling it left the sound modules installed until a reboot was
   carried out. Uninstallation or stopping the kernel modules should also unload them.
   This patch adds in the modprobe -r commands to unload all the snd modules installed
   with the start command. The stop command is then added into the uninstall script to
   remove the modules.
