Thanks, I did an initramfs hook that it adds the libraries mentioned in 
the previous email and changed the kernel configuration adding KPROBE=y 
and PROBE_EVENTS_BTF_ARGS=y and the Systemd's error message is gone.
Sadly now a warning instead is returned by Systemd:

systemd[1]: bpf-restrict-fs: Failed to link program; assuming BPF LSM is 
not available.

I was thinking to give up. Does anybody know which Systemd's features I 
lose if BPF and LSM are disabled in the Linux kernel? Is it a big 
trouble for the entire operating system?
