# Bogdan points out that: 'we will actually have d == "" in the echo example

# I'm not using any local names because its easier to not get confused

# resolve("/s1/a") can now have 4 possible objects, the mount point in server1,
# the mount point in server2, the mount point in server3, and the object d in
# server4.  When we make a call, like SetACL, how do we tell which one to
# modify?   If we glob("/s1/a") we get:
#
# "s1/a", ["/s2/b"(mountpoint)]
# "s1/a", ["/s3/c"(mountpoint)]
# "s1/a", ["/s4"(mountpoint)]
