bug#45633: bcc and bpftrace require kernel headers from system

[Tobias Geerinckx-Rice via Bug reports for GNU Guix]

John,

This reminds me of <http://issues.guix.gnu.org/45592>.

Hi Guix,


version of the kernel headers would be used.  After a few kernel

When I added bcc and bpftrace to guix I didn't think much of which updates, it has become clear that the current-system kernel headers need

This should probably be booted-system.

to match the kernel headers the packages are compiled with. Can they be

provided with a variant property?  The ocaml packages that need

headers.

different ocaml versions seem like a nice model on how to do the kernel

Kind regards,

I know exact kernel headers are needed at toolchain run time, when building eBPF programmes. Are they really needed at toolchain build time, too? That sounds wrong (but there are more things fundamentally wrong with eBPF on Linux; ask me to rant about CONFIG_IKHEADERS). Still, could pointing bcc/bpftrace to booted-system headers at run time not suffice?
