Thanks for your diagnosis.
You are right, /dev/null is missing in the opensuse basefile and that's what I am using.

>For now you can try to fix this in a hook using mknod.

I added the mknod command ("mknod --mode=666 /dev/null c 1 3") to the repository hook, right before calling fcopy the first time.

Strangely, it fails with "mknod: /dev/null: File exists". And then fcopy, the very next command, still complains
“Can’t open /dev/null: No such file or directory”.

Nevertheless, /target/dev/null now is present, with the same attributes as /dev/null .

Best,
Frank
