The first reason is that our current kernel package seems to have the "block" module built in now, so the udev rule which is meant to set the default in-kernel polling value doesn't work:

ACTION=="add", SUBSYSTEM=="module", KERNEL=="block", ATTR{parameters/events_dfl_poll_msecs}=="0", ATTR{parameters/events_dfl_poll_msecs}="2000"

This requires a sysctl.d setting now. Will add to udev package.

However, even when I set the polling interval manually, the kernel still doesn't emit an eject_request uevent, even though it claims to:

$ cat /sys/block/sr0/events
media_change eject_request

I still need to investigate that.
