Great idea, this could be added (at least) to all handlers that already have a "nicelevel" option. Notes to micah + myself : 1. The availability of the ionice command, and the fact it actually works, should be tested at runtime : such I/O priority classes are only supported since Linux kernel 2.6.13, with the CFQ io scheduler => this test code should be factorized in lib/, and not duplicated for all handlers. 2. ionice is part of the schedutils package, that should thus be added as a Suggest: when this feature will be implemented.
