Dear all, 

I'm recently running into a strange problem in the Gentoo release build automation, and need help.

We use parted to create label and partitions in a qcow2 image available via qemu-nbd.
  https://gitweb.gentoo.org/proj/catalyst.git/tree/targets/support/create-qcow2.sh#n96

This worked fine for quite some time.

Recently, it stopped working, there is no error message at all, but the command
  parted -s /dev/nbd0 mklabel gpt
returns 1. 

If I run the same command outside the release automation manually, the return code is 0 and
everything is fine.

I inserted strace to see what's wrong. The log follows- any ideas?

Thanks in advance,
Andreas
