I agree, but unfortunately, bash PS1 \h doesn't, and neither did the old 
GDM themes that showed hostname (although in their case the hostname 
probably hadn't been set because dm didn't wait for network-up).

Considering that modern networks come up in a fraction of a second, 
having dm depend on the network shouldn't really affect perceived boot 
time.  Maybe a better solution would be to have dm wait for a separate 
target like "dm-proceed", and let the network scripts for slow networks 
like dialup flip it prematurely if they like.  In other (most) cases, it 
could be flipped at the same time as network-up.
