Bug ID: 24629
Summary: document whether stapdyn works in containers
Product: systemtap
Version: unspecified
Status: NEW
Severity: minor
Priority: P2
Component: dyninst
Assignee: systemtap at sourceware dot org
Reporter: me at serhei dot io
Target Milestone: ---
Inside a Podman container I get:
sh-4.2# stap --dyninst -ve 'probe process.function("*") { println(pp()) }' -c
'ls'
Pass 1: parsed user script and 51 library scripts using

If this is fixable, I would like to fix it. But I would at least like to
identify the exact reason before we WONTFIX this.
