================================================================================
WHAT WAS MISSING - NOW SOLVED
================================================================================

❌ BEFORE: Scripts hardcoded mail commands
   exim -bpc          (only works on Exim)
   postqueue -p       (only works on Postfix)
   mailq              (only works on Sendmail)

✅ AFTER: Scripts use SYS_MAIL_CMD_* variables
   eval "$SYS_MAIL_CMD_QUEUE_COUNT"  (works on any MTA)
   eval "$SYS_MAIL_CMD_QUEUE_LIST"   (auto-detects mail system)

---

❌ BEFORE: Scripts hardcoded database paths
   /usr/bin/mysql             (MySQL only)
   /usr/bin/mysqldump         (MySQL only)

✅ AFTER: Scripts use SYS_DB_* variables
   $SYS_DB_CLI_COMMAND        (MySQL or PostgreSQL)
   $SYS_DB_DUMP_COMMAND       (auto-detects database type)

---

❌ BEFORE: Scripts assumed security tools
   /usr/bin/clamscan          (error if not installed)
   /usr/local/maldetect/maldet (error if not installed)
   /usr/bin/rkhunter          (error if not installed)

✅ AFTER: Scripts check and use available tools
   if [ -n "$SYS_SCANNER_CLAMAV" ]; then
       $SYS_SCANNER_CLAMAV -r /home
   fi

---

❌ BEFORE: Permission checks hardcoded UIDs
   if [ "$uid" -eq 48 ]; then      (RHEL only)
   if [ "$uid" -eq 33 ]; then      (Debian only)

✅ AFTER: Permission checks use detected UIDs
   if [ "$uid" -eq "$SYS_WEB_UID" ]; then
       echo "Owned by web server"   (works on all platforms)
   fi

================================================================================
MULTI-PLATFORM ABSTRACTION NOW COMPLETE
================================================================================

Scripts can now work on ANY combination of:

  ✅ Mail Systems: Exim, Postfix, Sendmail
  ✅ Databases: MySQL, MariaDB, PostgreSQL
  ✅ Control Panels: cPanel, Plesk, InterWorx, Standalone
  ✅ Linux Distros: RHEL, CentOS, AlmaLinux, CloudLinux, Ubuntu, Debian
  ✅ Web Servers: Apache (httpd/apache2), Nginx, LiteSpeed
  ✅ Firewalls: CSF, firewalld, iptables, UFW, Imunify360, Plesk
  ✅ Security Tools: ClamAV, Maldet, RKHunter, Imunify360

Without ANY hardcoding or platform-specific code!

================================================================================
HOW TO USE NOW
================================================================================

In any script:

  1. Source the variables:
     source "$SCRIPT_DIR/lib/system-variables.sh"

  2. Use SYS_* variables instead of hardcoded paths:
     # Mail
     eval "$SYS_MAIL_CMD_QUEUE_COUNT"

     # Database
     $SYS_DB_DUMP_COMMAND --all-databases > backup.sql

     # Security
     if [ -n "$SYS_SCANNER_CLAMAV" ]; then
         $SYS_SCANNER_CLAMAV -r /home
     fi

     # Permissions
     if [ "$uid" -eq "$SYS_WEB_UID" ]; then
         echo "Owned by web server"
     fi

================================================================================
NEXT STEPS
================================================================================

Optional: Update existing scripts to use new variables

Priority 1 (Easy, High Impact):
  [ ] modules/email/mail-queue-inspector.sh
  [ ] modules/email/mail-log-analyzer.sh
  [ ] modules/email/deliverability-test.sh

Priority 2 (Medium, High Impact):
  [ ] lib/mysql-analyzer.sh
  [ ] modules/performance/mysql-query-analyzer.sh

Priority 3 (Medium, Very High Impact):
  [ ] modules/security/malware-scanner.sh
  [ ] modules/security/bot-analyzer.sh

Priority 4 (Low Impact, Wide Reach):
  [ ] Search codebase for hardcoded UIDs (48, 33, 986)
  [ ] Replace with SYS_*_UID variables
