…#27878) partial fix for #27648 , this PR: Detects if the user is running as root then: Checks to see if an environment variable BEAT_SETUID_AS (set in our Docker.tmpl) is present Attempts to Setuid , Setgid and Setgroups to that user / groups Invokes setcap to drop all privileges except NET_RAW+ep This PR also fixes the broken syscall filtering in heartbeat, some non-syscall strings were breaking that. With the changes here elastic-agent can still run as root, but the subprocesses can lower their privileges ASAP. This should also make it possible for heartbeat to safely run ICMP pings and synthetics. Synthetics must run as non-root, but ICMP requires NET_RAW. This lets us be consistent in our docs with the recommendation that elastic-agent run as root.
