Note that this doesn't do anything for dependent packages like
debos, which will probably need similar dependencies.

What I proposed adding to fakemachine, which debos should probably also
get, are:

Architecture: amd64
Depends: busybox | busybox-static, qemu-system-x86, systemd
Recommends: e2fsprogs, linux-image-amd64

Thanks,

[pkg-go] Bug#898651: fakemachine: missing dependencies

[Simon McVittie]

Package: fakemachine
Version: 0.0~git20180126.e307c2f-1
Severity: grave
Justification: renders package unusable

In a relatively minimal (buildd) chroot:

smcv@archetype(sid-amd64):~$ sudo apt install fakemachine hello
...
smcv@archetype(sid-amd64):~$ fakemachine hello
2018/05/14 16:31:15 open failed: /bin/busybox - open /bin/busybox: no such file 
or directory
panic: open failed: /bin/busybox - open /bin/busybox: no such file or directory
smcv@archetype(sid-amd64):~$ sudo apt install busybox
...
smcv@archetype(sid-amd64):~$ fakemachine hello; echo $?
255
smcv@archetype(sid-amd64):~$ sudo apt install --no-install-recommends 
linux-image-amd64 qemu-system-x86
...
smcv@archetype(sid-amd64):~$ fakemachine hello; echo $?
...
Running hello
Hello, world!
Powering off.
[4.471990] reboot: Power down
0

fakemachine should have dependencies (or at least Recommends) on:

* busybox | busybox-static
* systemd
* linux-image-amd64 [1]
* qemu-system-x86   [2]

[1] Perhaps with linux-image-generic (Ubuntu), etc., as alternatives.
Upstream only supports x86_64 hosts, for which I've opened separate
bugs.
[2] Use of qemu-system-x86_64 is currently hard-coded.

By inspection of its source code, it should also have at least a Suggests
(probably a Recommends) on e2fsprogs, for mkfs.ext4.

Please consider the attached patch.

Thanks,
