[Libguestfs] [PATCH nbdkit 0/5] server: Add .get_ready callback.

[Richard W.M. Jones]

I like this change.  I think we were overloading the config_complete
method before to do two different things (complete configuration; do
any allocation/housekeeping necessary before we can start serving).

The only questions in my mind are whether we want this before 1.18,
and whether the name ("get_ready") is a good one.

Rich.
