I wish people would clearly distinguish "loop" devices from "loopback" devices. The word loopback appears nowhere in 'man losetup', nor in any actual command for a loop device, but somehow it has come into widespread use. Looback devices are part of the network system. Loop devices are part of the file system. "Loopback devices" are so named because they return data back up the network stack. See Linux/drivers/net/loopback.c "Loop devices" are so named because the filesystem driver accesses a higher level of the filesystem before descending again. As far as I am aware, there is no loop in data flow, only in the access path to it. As far as I am aware, there is no closed loop, only a return to a higher access level before descending again somewhere else. They are implemented by Linux/drivers/block/loop.c I am aware this usage is widespread. It has even infected loop.c $ uname -r 3.2.0-4-686-pae $ grep -i loopback loop.c | wc -l 1 $ grep -i loop loop.c | wc -l 322 However it feels quite wrong to me to not distinguish the two, because they are totally different things, with almost nothing in common. It is easily achieved. If I am overlooking something, please do feel free to correct me. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
