描述
According to https://github.com/systemd/systemd/issues/24204 https://github.com/systemd/systemd/blob/78208556b281bd6ee8a95d16a517152728010475/docs/CREDENTIALS.md?plain=1#L303
fw_cfg has a 55 bytes name length limit, and many systemd creds names are actually longer than that, e.g. opt/io.systemd.credentials/ssh.ephemeral-authorized_keys-all. SMBIOS is the new recommended way to pass in credentials.
