Looks good!  Here's what I did to make sure I am not doing something
wrong or whatever ...

I downloaded:

dracut-048-1.fc28.x86_64.rpm
dracut-config-rescue-048-1.fc28.x86_64.rpm
dracut-network-048-1.fc28.x86_64.rpm

# dnf install dracut*048*rpm

(which picked up two dependencies:

libkcapi.x86_64 1.1.1-1.fc28
libkcapi-hmaccalc.x86_64 1.1.1-1.fc28

then I moved /boot/initramfs-4.17.3-200.fc28.x86_64.img aside

did 

# dracut -v --kver 4.17.3-200.fc28.x86_64

then rebooted with:

/vmlinuz-4.17.3-200.fc28.x86_64
root=UUID=938086a8-c6ef-41ce-9225-bcb23221dbe9 ro
rd.md.uuid=e40a0234-7e52-5f10-f267-658d8ec463fa 
...

so i think all is well, thanks!
