Interesting! My idea would have been different, based on my presumption that 
the amount of devices on a 9p exported tree should be very small, whereas the 
amount of total files/dirs could be very high, I would have probably encoded as 
many bits as possible for the inode part and would have consecutively 
generated short device IDs as prefixes instead.

But I see that you already have a consensus to go into the direction suggested 
by Antonios.

Question: so far I just had a look at that patch set, but haven't tried it 
yet. Am I correct that the inode numbers (of the same file) would actually 
change on guest side with every reboot (i.e. depending on the precise sequence 
individual files would be accessed by guest after each reboot)?

Is there still anything substantial missing in that patch set?
