Hey John,

Thanks for your patience!

Yes, I tested some of them, looks fine :).

Actually, I wonder if we could mount debugfs by default, by adding it to
%base-file-systems. Any objections?

In the meantime I pushed the bcc patch with a few edits. Regarding
bpftrace, I'd like to avoid the "-DHAVE_BFD_DISASM=OFF" patching, I
found this ticket which seems related:
https://github.com/iovisor/bpftrace/issues/1106, but didn't make any
significant progress yet.

Thanks,

Mathieu
