+# DEVELOPERS NOTE:
+# Network Debugging:
+# - bind-tools - DNS utilities (dig, nslookup, host) - Critical for your current issue!
+# - iputils - Network utilities (ping, traceroute)
+# - netcat-openbsd - TCP/UDP connection testing (nc command)
+# - busybox-extras - Additional networking tools (telnet, etc.)
+#
+# Process Debugging:
+# - strace - System call tracer (debug what the app is doing)
+# - procps - Process utilities (ps, top, etc.)
+# - htop - Interactive process viewer
+#
+# Shell & Editing:
+# - bash - Full bash shell (better than ash)
+# - nano - Simple text editor
+# - vim - Advanced text editor
+
+# File Transfer:
+# - wget - Download files (alternative to curl)
