Comment 82 for bug 579300

Why not a separate package (let's call it "ossemul-deprecate.dpkg"), shipped with the stock ubuntu, which contains just a file:

/etc/modprobe.d/blacklist-ossemul.conf

with "blacklist snd_pcm_oss" inside? (eventually add other oss emulation modules if opportune)

It would disable oss emulation by default, but still if, for any reason, one would like to get oss emulation back, he should just uninstall the above package (through CLI, GUI or anything) and would be up and running in a matter of seconds.
This would avoid any dkms compile complication or source misalignment, and it would require 0 manutention effort.

Also (desiderable, but not needed) packages known *not* to work without oss emulation could be marked conflicting with that package, such preserving usability during with the oss dismission plan.

Wouldn't anyone be happy in this way? If not could the maintainers please explain if (and why) such solution is not applicable?
