So at the moment we have the following setup:

- keyfile - not needed; at the moment we don't support any medium that 
needs a keyfile
- /etc/resolv.conf - NetworkManager writes to 
/run/NetworkManager/resolv.conf , and the onus has always been on the 
integrator to create a sym-link from /etc/resolv.conf to /run
- /etc/NetworkManager/NetworkManager.conf - fixed file
- /etc/NetworkManager/system-connections/ - sym-linked to 
/var/lib/NetworkManager/system-connections/
- /etc/hostname - sym-linked to /var/lib/hostname

...and that all works fine; apart from writing the hostname back through 
the sym-link.

Like I say, I think this patch is fixing something real. If I did this...

# echo myhost > /etc/hostname

...with a sym-link, that would write through to the target of the 
sym-link, rather than replacing it with a file. That's the behavior I 
would expect.
