My take on it though is that it's a reasonable request. It's much like there is "sort -u" even though you could do this via "sort | uniq". Part of the Unix philosophy is to use tools that are composable, yes --- but optimizing for common cases is also a good thing, and with the advent of virtualization being more and more popular, zeroing free blocks for virtualization images is good and useful thing. This is also why I agitated for adding support so that e2fsprogs tools could operate directly on qemu-img files, and not just have support which is hacked into e2image. Yes, you can always take an qemu-img file, decompress and expand it into a raw file, run debugfs or e2fsck on it, and then convert it back to a qemu-img file --- but if lots of people are doing that, it does make sense to optimize for the most common use cases. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
