I've forwarded this upstream to https://github.com/systemd/systemd/issues/13417 where it was mentioned that this topic had already come up and the fix was to document this limitation. See https://github.com/systemd/systemd/pull/11989/commits/6cc68362d529ca8b99fd6ca55b0fc7143e696aea Have you seen this paragraph in systemd-nspawn? I invite you to join the upstream bug tracker if you have further feedback. Otherwise I'm going to close this bug report as this limitation is actually documented: > Note that on Linux network interface names may have a length of 15 > characters at maximum, while container names may have a length up to 64 > characters.
