# losetup -o 2048 /dev/loop0 /dev/scd0
ioctl: LOOP_SET_STATUS: Invalid argument
without `-o 2048' the loopback works fine (but is useless because I need to skip
the first sector;). strace shows:
# strace losetup -o 2048 /dev/loop0 /dev/scd0
...
open("/dev/scd0", O_RDWR) = -1 EROFS (Read-only file system)
open("/dev/scd0", O_RDONLY) = 3
open("/dev/loop0", O_RDONLY) = 4
ioctl(4, LOOP_SET_FD, 0x3) = 0
ioctl(4, LOOP_SET_STATUS, 0xbffff500) = -1 EINVAL (Invalid argument)
ioctl(4, LOOP_CLR_FD, 0) = 0
write(2, "ioctl: LOOP_SET_STATUS: Invalid "..., 41ioctl: LOOP_SET_STATUS: Invalid argument) = 41
