This doesn't work with full disk encryption. Unit file does not get
generated and I see this message:

[    7.142993] testhost dracut-initqueue[202]: Failed to start systemd-cryptsetup@luks\x2d342d2414\x2d159c\x2d48d7\x2da0b7\x2d5b59fa6e27a5.service: Unit 
systemd-cryptsetup@luks\x2d342d2414\x2d159c\x2d48d7\x2da0b7\x2d5b59fa6e27a5.service failed to load: No such file or directory.

Probably this is because crypt-run-generator get executed from udev
rules only if *both* of the following conditions are true:
- there is no rd.luks.uuid parameter in both cmdline
and /etc/cmdline.d/*.conf
- rd.auto is enabled
