Package: systemd-container Version: 239-14 Severity: important Dear Maintainer,
Current systemd-nspawn fails to start a container when going through the systemd machine target or using machinectl. I'll illustrate this using a debian stable debootstrap. I found a thread discussing similar issues on systemd >= 239 for other host systems and/or other guest containers that lead me to: https://github.com/systemd/systemd/issues/10026 I eventually applied the corresponding upstream patch fixing the issue: https://github.com/systemd/systemd-stable/commit/3371efc365046b5ed9921ab80687f5add81bdc16 Reproduction steps ================== # as root, i don't have a big /, so i'll be using /home. Do as you see fit $ mkdir -p /home/chroots $ cd /home/chroots $ debootstrap stable stable [... does its work successfully ... ] $ ln -sf /home/chroots/stable /var/lib/machines/stable $ systemctl enable machines.target $ systemctl enable systemd-nspawn@stable # then this last command is executed w/ patched or unpatched # systemd-container package $ machinectl start stable # or $ systemctl start systemd-nspawn@stable Results without patch, the container doesn't start ================================================== root@WKS-423P992-LN:/home/ed/tmp/systemd# machinectl status stable stable(60ba5d8188c044eb9de0abab8c67ddcb) Since: Mon 2018-12-03 14:14:51 CET; 3s ago Leader: 14714 (systemd) Service: systemd-nspawn; class container Root: /home/chroots/stable Iface: ve-stable OS: Debian GNU/Linux 9 (stretch) UID Shift: 1309540352 Unit: systemd-nspawn@stable.service ├─payload │ └─14714 /lib/systemd/systemd └─supervisor └─14712 /usr/bin/systemd-nspawn --quiet --keep-unit --boot --link-journal=try-guest --network-veth -U --settings=override Dec 03 14:14:51 WKS-423P992-LN systemd-nspawn[14712]: [1B blob data] Dec 03 14:14:51 WKS-423P992-LN systemd-nspawn[14712]: Welcome to Debian GNU/Linux 9 (stretch)!
