I don't agree with the "highly limited in impact", but I do agree with the compromise of putting the udev rule into kubuntu-default-settings. While this isn't an appropriate long-term solution (i. e. it definitively shouldn't be done that way in Utopic or at least not in V), I don't know of a more appropriate place for an SRU. > Would the technical board support a swifter resolution of the problem > or indeed prefer waiting? I think we shouldn't wait with landing that change in -proposed, but do it now so that we can start collecting feedback and doing measurements on this. This will require quite extensive verification/testing on various hardware, which certainly won't be done by next week. This should include some positive results for KDE+balloo on HDD, confirm that the scheduler isn't changed for KDE+balloo on SSD, and that running Unity/zeitgeist with kubuntu-default-settings installed doesn't show a significant regression (some minor timing changes are acceptable, I think).
