There's been a fair amount of research into this - see http://www.soe.ucsc.edu/~tbisson/papers/bisson-fast04.pdf for instance. Some laptop drives will behave this way if APM settings are set appropriately, but a decent implementation of this in userspace would be very nice. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
