Yep.

chroot launched as

QEMU_CPU=cortex-a15
LC_ALL=C
/usr/sbin/qemu-binfmt-conf.sh
chroot ${CHROOT} /bin/bash

ps ax | grep qemu | grep pts
15193 pts/1    Sl+    0:09 /usr/bin/qemu-arm -0 /bin/bash /bin/bash

rpm -q --whatprovides /usr/bin/qemu-arm

> That's a QEMU error message, it appears.  QEMU 2.9.1 *looks* as if it
supports FS_IOC_GETFLAGS, so maybe you need a newer version of QEMU on
which to run Raspbian8.

As per above, I *do* have a newer version ... 2.10.1

> What's happening is probably that whatever program is building the zip
file is making FS_IOC_GETFLAGS ioctls to get additional file flags for the
files it's putting into the zipball.  That program probably has no problem
with FS_IOC_GETFLAGS being unsupported, as it's not supported by all file
systems on Linux, so it *has* to be able to handle not being able to get
those additional file flags.

Considering that 2.10.1 is, per https://www.qemu.org/, the latest release
as of Oct 2nd 2017, options for newer are a bit thin atm ...
