find_bwrap

Function find_bwrap 

Source
pub fn find_bwrap() -> Option<PathBuf>
Expand description

Locate the bwrap binary.

Checks a fixed list of trusted system paths first, because they’re owned by root on every mainstream Linux distro and therefore can’t be planted by a non-privileged attacker. Only if none of those exist does the search fall back to walking $PATH — at which point a tracing::warn! fires (once per process) so operators can notice that isolation is trusting an attacker-plantable lookup.

Returns None if bwrap is not installed anywhere we know to look.
