Protect nsswitch.conf and resolved.conf from hosts bypass - Add enforce-resolved.sh: validates ReadEtcHosts=yes, prevents DNSOverTLS bypass, removes drop-in overrides, locks drop-in dir - Add resolved-guard.path/service: watches /etc/systemd/resolved.conf and its drop-in directory for tampering - Update pacman hooks to unlock/relock nsswitch.conf and resolved.conf alongside /etc/hosts during package transactions - Extend setup_hosts_guard.sh with --skip-resolved option, resolved canonical snapshot, drop-in directory locking, and enforcement - Add resolved.conf checks to check_and_enable_services.sh: validates ReadEtcHosts, DNSOverTLS, drop-in overrides, immutable attribute, and resolved-guard.path status with auto-fix capability Fixed on live system: ReadEtcHosts was set to 'no' and nsswitch.conf was missing 'files' in the hosts line, completely bypassing /etc/hosts. 2026-02-20 23:21:25 +01:00			`[Unit]`
