Right. There's still a problem with kprobe and execsnoop. However,
this patch does fix some other scripts that are using awk and getconf.
> Any idea why?
The only thing I can think of is that the symbol used by execsnoop for
instrumenting the kernel was changed and is not in /proc/kallsyms. I'll
try to dig that later this week.

I went ahead and applied a modified version of this patch that uses
‘search-input-file’ instead of ‘which’.
Thanks,

Thanks Ludo! Olivier, any progress on the execsnoop issue :) ?

Nope. I did not had time to check it again sorry :-/
Maybe there's somehing missing on the kernel side. I will would check
that /sys/kernel/debug/tracing/events has the tracepoints used by
execsnoop and that the tracers ftrace and kprobe are correctly
configured.
