[Qemu-devel] glibc "linux: spawni.c: simplify error reporting to parent" breaks qemu-user/Windows Service For Linux

[John Paul Adrian Glaubitz]

Hi Rasmus!

Your recent commit "linux: spawni.c: simplify error reporting to parent" 
apparently
broke both qemu-user and Microsoft's Windows Services for Linux which both fail
with:

dpkg: warning: ignoring pre-dependency problem!
Preparing to unpack .../archives/bash_4.4-5_m68k.deb ...
preinst: ../sysdeps/unix/sysv/linux/spawni.c:366: __spawnix: Assertion `ec >= 
0' failed.
qemu: uncaught target signal 6 (Aborted) - core dumped
dpkg: error processing archive /var/cache/apt/archives/bash_4.4-5_m68k.deb 
(--unpack):
 new bash package pre-installation script subprocess was killed by signal 
(Aborted)
Selecting previously unselected package bsdutils.
dpkg: regarding .../bsdutils_1%3a2.30.2-0.1_m68k.deb containing bsdutils, 
pre-dependency problem:
 bsdutils pre-depends on libsystemd0
  libsystemd0 is not installed.

I'm not sure yet what the actual problem is but I thought it should be necessary
to point you at the problem.

Cheers,
Adrian
