The kernel knows about a mknod-created loop device once you use losetup. # ls1 /dev/loop* /dev/loop0 /dev/loop1 /dev/loop2 /dev/loop3 /dev/loop4 /dev/loop5 /dev/loop6 /dev/loop7 /dev/loop-control # mknod -m 660 /dev/loop99 b 7 99 # ls1 /dev/loop* /dev/loop0 /dev/loop1 /dev/loop2 /dev/loop3 /dev/loop4 /dev/loop5 /dev/loop6 /dev/loop7 /dev/loop99 /dev/loop-control # find /sys -name loop99 # losetup /dev/loop99 disk.img # find /sys -name loop99 /sys/devices/virtual/block/loop99 /sys/block/loop99 /sys/class/block/loop99 -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
