machinectl bind-volume MACHINE PROVIDER:VOLUME[:CONFIG][:K=V,...]
machinectl unbind-volume MACHINE PROVIDER:VOLUME
For bind-volume, machinectl parses the SPEC with the shared
bind_volume_parse(), Acquires the storage volume from the named
provider on the machinectl side, locates the target machine's
io.systemd.MachineInstance control socket via
machine_get_control_address(), pushes the fd across, and calls
io.systemd.MachineInstance.AddStorage with name='<provider>:<volume>'
and the user-supplied config string.
For unbind-volume, machinectl just forwards the name string to
io.systemd.MachineInstance.RemoveStorage.
Volumes attached at machine startup (e.g. via systemd-vmspawn's
--bind-volume=) are rejected with StorageImmutable when the user
attempts to unbind them at runtime.
