Bug ID: 242048
Summary: etcupdate should acquire lock to avoid racing with
another instance
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: b...@freebsd.org
Reporter: delp...@freebsd.org
Currently etcupdate(8) does not acquire any lock prior to operation, but the
operations are not re-entrant safe, for example, if the administrator performs
another 'etcupdate' in a different SSH session, the etcupdate state would be
damaged.
