do a rd.break=initqueue and look in the
/lib/dracut/hooks/initqueue/finished
directory.

If you use systemd in the initramfs, you should have:

/usr/lib/systemd/system-generators/dracut-rootfs-generator

in the initramfs, which transforms root=UUID=... into the finished hook.

You should be able to test it in the dracut shell with:

# bash -x /usr/lib/systemd/system-generators/dracut-rootfs-generator
