It would be nice if you could do "grep 1 /sys/block/*/burns_cds" and get a list of all the block devices in your system that burn cds. (You can currently get a list of all of the removable block devices in your system, but not much else.) The kernel must know a bunch of this sort of stuff, and it would be nice if the information available. (In fact, there's a lot that's in /proc/ide that isn't in /sys, which is a bit annoying, since it would be useful in /sys, especially if it would mean that you could ignore details of what kind of bus things were on.) -Daniel - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
