systemd Secure boot integration
sicher*boot automatically installs systemd-boot and kernels for it into the ESP, signed with keys generated by it. The signing keys are stored unencrypted and only protected by the file system permissions. Thus, you should make sure that the file system they are stored (usually /etc) in is encrypted. After installing sicherboot, you can adjust a number of settings in /etc/sicherboot.conf and should set a kernel commandline in /etc/kernel/cmdline. Then run ‘sicherboot setup’ to get started.
