It was the default action, but it was changed to 'change' because 'add' must not be used anywhere else than once after bootup. Triggering 'change' has some valid use cases, not many though, and most of them are workarounds for broken things. Settle is only needed to block until broken subsystems catch up with reality during bootup, and with reality how hotplug systems work today. It is not pulled-in for systems which do not run broken or legacy tools. o Yes, that changed May 2010 with udev 154.
I just upgraded to udev-181 and the issue still is there. I believe the /dev/mapper/ nodes are created by kernel's devtmpfs but the /dev/dm-* are created by cryptsetup and lvm running in initramfs where is no udev running. Even if I umount devtmpfs on initramfs level and let udev mount it again, the changes will be still there. (I do mount --move to /newroot/dev). Maybe the 'action=add' should care about already-created nodes as well?
