This can just as well be done by running "touch" to create an empry file, but I think it would be nice if one would use tgtimg for all devices. I would then create similar code for tgtimg to create a disk device. Just creating the file and writing zero to the entire file, just like dd would do. Metadata is a different topic. As you say, xattr is difficult to use in a unified way to store things because of SSC requiring so much metadata. I will leave metadata in targets.conf for now until there is consensus on how to handle it in an acceptable way for MMC and SBC. Perhaps one could use *.tgtd-metadata files to store the metadata for MMC and SBC devices isntead of xattr? regards ronnie sahlberg -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
