systemd smbios-type-11 7 smbios-type-11 SMBIOS Type 11 strings /sys/firmware/dmi/entries/11-*/raw Various OS components process SMBIOS Type 11 vendor strings that a virtual machine manager (VMM) may set and a virtual machine (VM) receives. SMBIOS Type 11 vendor strings may play a similar role as kernel-command-line1 parameters but generally are under control of the VMM rather than the boot loader or UKI. For details on SMBIOS Type 11 see the System Management BIOS specifications. The following strings are supported: io.systemd.credential:CREDENTIAL=VALUE io.systemd.credential.binary:CREDENTIAL=VALUE This allows passing additional system credentials into the system, in textual or binary (Base64) form. See systemd.exec5 and System and Service Credentials for details. io.systemd.stub.kernel-cmdline-extra=CMDLINE This allows configuration of additional kernel command line options, and is read by the kernel UEFI stub. For details see systemd-stub1. systemd1, kernel-command-line7, systemd.system-credentials7
