Also the VIA MiniITX boards usually come with
this kind of support which you may not want to use.
In the bug report I proposed a way to test for the presence of a sound card. Would embedded systems give "true" for that test? 

For VIA EPIA ME6000 (MiniITX):

Is there a test that could be used to exclude embedded systems?


Not a good idea.

Embedded system are also used for home entertainment and car navigation.

Only the admin can decide, which features should be installed.
A medium expert mode during installation would be nice. This could ask, what the system is intended to be used. If it is [File-|Web-|Mail-Server|Router|Firewall] the sound modules (and maybe others too) could be left out. But on a deeper level, the admin maybe wants to decide to install snd_*, e.g. to receive an accoustic time signal as ntp-reference (but this is exotic;-).
E.g. my VIA EPIAS run in a server cluster, have no floppy, no CD-ROM, parport is unused etc. I could customize the kernel and the module configuration, but I need not.
