Hi svellis,

while I've not yet had a chance to toy with z/VM Linux, the typical "\" vs. "/" problem comes to mind: On Unix, "\" is interpreted as an "escape character" to i.e. enter special characters. Have you tried using the Unix-typical path separator character "/" (forward slash) instead?

So the complete resource name, as seen from Linux, might be //yourlaptopname/D/boot/s390x. That'd be "yourlaptopname" as the host, "D" as the share and "/boot/s390x" as the directory name.
