What about something like: systemd requires the following options to be enabled in the kernel: - CONFIG_<foo> - CONFIG_<bar> These options will be automatically enabled by Buildroot if it is responsible for building the kernel. Otherwise, if you are building your kernel outside of Buildroot, make sure these options are enabled. Thomas
