One thing to lookout for is 'gluster poll', which is quite special, it should probably
try all addresses returned by getaddrinfo, for small installations (< 20 machines, say)
one could give all machines the same alias name, and mounting with that alias name
would work automagically even with some machines down, since mounting would try until
it found a responding machine, but the 'gluster poll' on that alias name would probably
break things if not anticipated before. Just my 5 ¢.
