Do you have some instructions somewhere how to get qemu-user working with
sbuild?
Have you seen #983087 which I fixed yesterday?
Thanks, but it doesn't help, unfortunately.
Do I need to use qemu-user-static or qemu-user-binfmt?
Oh. You tried to use qemu-user, not qemu-user-static..
Well.
In order for it to work it should be registered with the
in-kernel binfmt-misc subsystem. qemu-user-static package
does this automatically for you, but qemu-user does not,
for that with qemu-user you'll have to additionally install
qemu-user-binfmt package.
But I guess it wont work with qemu-user even if it is registered
(by means of installing qemu-user-binfmt or manual registration
or whatever), - because regular qemu-user binaries aren't
statically linked and hence require all the shared libraries
within the chroot in order to run.
I never tried to use regular (non-static) qemu-user with
foreign chroot, and I suspect it wont work because of that
very reason, and at least extra setup is needed (like
copying appropriate /lib/ld.so and libc&glib&Co to the
chroot).
This is all about how qemu-user works, be it debian or
any other distribution, - it is basically the same.
I can only guess the wiki page you mentioned is wrong
here.
