Description Jon 2020-08-04 07:41:46 UTC

Description of problem:
Seems like because the symbols of /bin/bpftrace are stripped some tools cannot be used.

i.e:
$ sudo ./opensnoop.bt 
Attaching 6 probes...
Could not resolve symbol: /proc/self/exe:BEGIN_trigger


Version-Release number of selected component (if applicable):
bpftrace.x86_64                                   0.11.0-1.fc32

How reproducible:
Always

Steps to Reproduce:
1. sudo ./opensnoop.bt 

Actual results:
Attaching 6 probes...
Could not resolve symbol: /proc/self/exe:BEGIN_trigger

Expected results:
Monitoring table output...

Additional info:
