Package: qemu-user-static
Version: 1:2.8+dfsg-6
Severity: normal
Dear Maintainer,
* What led up to the situation?
Attempting to build an `arm32v7/debian` derivative image with Docker's
distribution of docker-ce(which fails with out-of-the-box Debian 9).
* Other symptoms:
The systemd-binfmt.service file fails to activate properly due to the
missing directory contents listed.
```
computermouth@desktop:~$ systemctl status systemd-binfmt

* What exactly did you do that was effective?
Fedora 26 includes the following files with their qemu-user-static package:
```
qemu-aarch64-static.conf
qemu-alpha-static.conf
qemu-armeb-static.conf
qemu-arm-static.conf
qemu-cris-static.conf
qemu-m68k-static.conf
qemu-microblazeel-static.conf
qemu-microblaze-static.conf
qemu-mips64el-static.conf
qemu-mips64-static.conf
qemu-mipsel-static.conf
qemu-mips-static.conf
qemu-ppc64abi32-static.conf
qemu-ppc64-static.conf
qemu-ppc-static.conf
qemu-s390x-static.conf
qemu-sh4eb-static.conf
qemu-sh4-static.conf
qemu-sparc32plus-static.conf
qemu-sparc64-static.conf
qemu-sparc-static.conf
```
These files include the binfmt magic strings for instruction translation.
I.e:
```
computermouth@desktop:/lib/binfmt.d$ cat qemu-arm-static.conf
:qemu-
arm:M::\x7fELF\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x28\x00:\xff\xff\xff\xff\xff\xff\xff\x00\x00\x00\x00\x00\x00\x00\x00\x00\xfe\xff\xff\xff:/usr/bin/qemu-
arm-static:F
```
I copied those to my Debian host and viola! I can now build Docker
containers for different architectures.
* Notes
I can't seem to find the source for these files in either Debian's or
Fedora's package source, nor in the upstream qemu source.
