Package: qemu-user-static
Version: 1:2.5+dfsg-5
Severity: important
Dear Maintainer,
I just created a fresh mips schroot using qemu-debootstrap to emulate mips
architecture.
Unfortunately, I cannot resolve any name because it seems DNS resolution is not
working anymore. Attached is strace log of a simple ping against ftp.debian.org
This behaviour happens at least under mips, mipsel and s390x.
