Hm, maybe. How does it remind you of zfs? It seems like zfs needs the libraries from util-linux, right? bcc and bpftrace need the kernel headers. The following should illustrate there is nothing to load dynamically, right? find $(guix build linux-libre-headers) -name '*.\.so*' > This should probably be booted-system. Yes, definitely, thanks. s/current-system/booted-system/ > I know exact kernel headers are needed at toolchain run time, when > building eBPF programmes. Are they really needed at toolchain > build time, too? I am not sure what the headers are used for but they are indeed the .h files (tree $(guix build linux-libre-headers)). I would assume they are used by the gcc-toolchain when compiling the package as #includes. What do you think? - John
