No interest in util-linux compatibility?
Is util-linux really creating the device node?
I thought it would use the current /dev/loop-control API and request a
new device from the kernel, which then is created via udev.
You are right. I didn't think about udev, just saw different behavior.
But in the end I think it doesn't really matter if udev or losetup creates
the device. Losetup expects the device to be created somwhere in
/.../loop#### anyway (with the path given by the caller). If the path
was wrong,
but still ended in /loop####, the device is created using the
loop-control and
not used afterwards. I am not sure what the upside of using udev is here.
But as far as compatibility is concerned, it would probably be better, if
busybox uses loop-control with LOOP_CTL_ADD as well.
