+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.
