Hi,

I think the confusion with the device id comes from that fact that I  
posted the results from two different boots:

1.) Trying to boot from the Fedora 21-Alpha with the contained initrd  
image -> waits forever for /dev/ubdb1 resp. /dev/ubdb3, which are the  
partitions on the ISO image
2.) Boot from a Fedora 21 alpha installation, which waits forever for  
device with UUID 008af19d-2562-49bd-8907-721ea08f3e14, which is  
/dev/ubda1, which contains the /boot partition

the error happens in both situations, so I thought I shouldn't matter  
which one to post.

anyway, here is the info you asked for:
# systemctl status
