Suggestions on how to make it less messy would be welcome.
If you have permissions to chroot,
you generally have permissions to set binfmt_misc too. Alternatively
these kind of exec manipulations are already done by external tools like
proot and scratchbox.
True. Though I would say that's quite a convoluted solution compared to
this patch.
The issue I encountered came when I was trying to run ARM gstreamer unit
tests. libgstreamer runs the gst-plugin-scanner helper executable at
startup to scan for plugins. However it took me a long time to figure
this issue out because in the current behavior linux-user doesn't make
it clear what qemu will run all child processes on the host even if they
are a different arch.
Adding these patches offers the choice, and makes the situation clearer
to the user.
However if you are ready to stay around to maintain it, and nobody else
objects the code, I can merge it.
I'll be around for the time being certainly.
