Package: systemd Version: 228-2+b1 Severity: normal This particular issue arises from this documentation: http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
It may also be related to #789439. I adapted vmdebootstrap to mask udev's rule file, as advised in the first of the documented methods of disabling this support. "You disable the assignment of fixed names, so that the unpredictable kernel names are used again. For this, simply mask udev's rule file for the default policy: ln -s /dev/null /etc/udev/rules.d/80-net-setup-link.rules" http://git.liw.fi/cgi-bin/cgit/cgit.cgi/vmdebootstrap/tree/vmdebootstrap/base.py?id=vmdebootstrap-1.3#n208 That worked during testing. Since releasing that change, systemd has apparently dropped support for this method and a VM built with this change no longer raises a network interface using DHCP. $ sudo vmdebootstrap --image=sid.img --distribution=unstable --grub --enable-dhcp --verbose QEMU is capable of booting images with different network configurations, so it is not simple for vmdebootstrap to know in advance what names systemd will generate - hence the change to assert the previous behaviour. vmdebootstrap is also used to generate images for use on ARM dev boards like beaglebone-black and cubietruck, so having a consistent interface that can be configured to use DHCP at boot is important. -- Package-specific info: -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386, armhf, arm64 Kernel: Linux 4.2.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages systemd depends on: ii adduser 3.113+nmu3 ii libacl1 2.2.52-2 ii libapparmor1 2.10-2+b2 ii libaudit1 1:2.4.5-1 ii libblkid1 2.27.1-1 ii libc6 2.21-6 ii libcap2 1:2.24-12 ii libcap2-bin 1:2.24-12 ii libcryptsetup4 2:1.6.6-5 ii libgcrypt20 1.6.4-4 ii libkmod2 22-1 ii liblzma5 5.1.1alpha+20120614-2.1 ii libmount1 2.27.1-1 ii libpam0g 1.1.8-3.1 ii libseccomp2 2.2.3-2 ii libselinux1 2.4-3 ii libsystemd0 228-2+b1 ii mount 2.27.1-1 ii sysv-rc 2.88dsf-59.2 ii util-linux 2.27.1-1 Versions of packages systemd recommends: ii dbus 1.10.6-1 ii libpam-systemd 228-2+b1 Versions of packages systemd suggests: pn systemd-container <none> pn systemd-ui <none> Versions of packages systemd is related to: ii udev 228-2+b1 -- no debconf information
