+# Teleport VNet Linux Files
+
+This directory contains files needed for VNet to work on Linux.
+Teleport Connect ships these files in its package.
+
+## Files
+
+- `teleport-vnet.service`: systemd unit for the privileged VNet daemon.
+- `dbus/org.teleport.vnet1.conf`: D-Bus system bus policy for `org.teleport.vnet1`.
+- `dbus/org.teleport.vnet1.service`: D-Bus service activation entry for `org.teleport.vnet1`.
+- `polkit/org.teleport.vnet1.policy`: polkit policy used to authorize starting and stopping the privileged VNet daemon.
+
+## Install locations (package defaults)
+
+- `teleport-vnet.service` -> `/usr/lib/systemd/system/teleport-vnet.service`
+- `dbus/org.teleport.vnet1.conf` -> `/usr/share/dbus-1/system.d/org.teleport.vnet1.conf`
+- `dbus/org.teleport.vnet1.service` -> `/usr/share/dbus-1/system-services/org.teleport.vnet1.service`
+- `polkit/org.teleport.vnet1.policy` -> `/usr/share/polkit-1/actions/org.teleport.vnet1.policy`
+
+Notes:
+- For packaged vendor files, `/usr/share/...` is the standard location.
+- `/etc/dbus-1/system.d/` is typically for local admin overrides, not vendor package files.
+
+## Manual install example
+
+```bash
+sudo cp teleport-vnet.service /usr/lib/systemd/system/teleport-vnet.service
+sudo cp dbus/org.teleport.vnet1.conf /usr/share/dbus-1/system.d/org.teleport.vnet1.conf
+sudo cp dbus/org.teleport.vnet1.service /usr/share/dbus-1/system-services/org.teleport.vnet1.service
+sudo cp polkit/org.teleport.vnet1.policy /usr/share/polkit-1/actions/org.teleport.vnet1.policy
+sudo systemctl daemon-reload
+sudo dbus-send --print-reply --system --dest=org.freedesktop.DBus /org/freedesktop/DBus org.freedesktop.DBus.ReloadConfig
