just add an info function to the client and query it from the script :)
(ldminfo in reverse ...)

Bug description:
Currently nbd-server and nbd-client communicate using a different port for each image. So if e.g. an LTSP admin wants to use a chroot for nvidia-based clients and a chroot for the rest of his clients, he'd need to use two ports. And he wanted nbd swapping a third port would be needed.

This is inconvenient and makes IANA applications to standarize the nbd port impossible.
It'd be better if nbd-client supported two additional parameters, to be sent and processed by nbd-server at the negotiation stage:
 * A -path=/path/to/desired/root option (which of course the server could ignore, if it wasn't in a pool of allowed paths), and
 * A -swap=<requested size> option (to replace the current -swap option). If the server configuration allowed it, nbd-server (or some callback scripts) would create an appropriate swap flie of that size for the client.
