Package: libseccomp Version: 2.3.1-2 Hi,
pdns.service (from pdns-server in testing) didn't start anymore with this message: pdns.service: Failed at step SECCOMP spawning /usr/sbin/pdns_server: Invalid argument Updating libseccomp2 from 2.1.1-1 (stable) to 2.3.1-2 (testing) fixed it. systemd 232-3 has a build dependency `libseccomp-dev (>= 2.2.3-3~)`, but the resulting package only depends on `libseccomp2 (>= 2.1.0)`. I guess systemd uses a feature from newer libseccomp versions which wasn't tracked by the symbols file. Maybe you should consider upgrading the minimum versions in the symbols file. (Probably broken in backports too.) regards, Stefan
