This is particularly relevant for systemctl, as it will not alter its behaviour for `chroot()` environments if set. Normally it refrains from talking to PID 1 in such a case; turning most operations such as `start` into no-ops. If that's what's explicitly desired, you might consider setting `$SYSTEMD_OFFLINE=1`. -Topi

Combined with IPVLAN or similar (which systemd-nspawn makes easy) you can bring up a namespaced network interface inside the container completely isolated from the host. I do this for various setups and it works pretty well. Col

Because you don't have systemd as init while inside a chroot. 2) How can I start the network using systemd? > Start it outside the chroot. -- Mantas Mikulėnas
[systemd-devel] Q: Start network in chroot?
Hi! Two questions: 1) Why can't I use "systemctl start network" in a chroot environment (e.g. mounting the system from a rescue medium to fix a defective kernel)? When I try I get: "Running in chroot, ignoring command 'start'" 2) How can I start the network using systemd? (systemd-246-16 of SLES15 SP3) Regards, Ulrich
