| The Raspberry Pi Trixie OS has adopted [[https://www.raspberrypi.com/news/cloud-init-on-raspberry-pi-os/|cloud-init]] for first boot initialization, and the latest Raspberry Pi imager has removed the ability to customize custom OS images. Therefore, to customize the OS prior to booting (e.g. changing the default userid/password, adding authorized SSH keys, etc.) please edit the //user-data// file according the the instructions in the [[https://docs.cloud-init.io/en/latest/index.html|cloud-init documentation]] | The Raspberry Pi Trixie OS has adopted [[https://www.raspberrypi.com/news/cloud-init-on-raspberry-pi-os/|cloud-init]] for first boot initialization, and the latest Raspberry Pi imager has removed the ability to customize custom OS images.

This is useful when the original path must remain a normal file or directory, or when the application does not work well with symbolic links. | A bind mount can also be used to make a file on the //datafs// partition appear at its original location on the //rootfs// partition.

| | ==== .NET 10 ==== |
| | |
| | The .NET 10 SDK and Microsoft’s Visual Studio Remote Debugger (//vsdbg//) are installed by default, so .NET development should be ready to go out of the box. |
| | |
| | Now that [[https://learn.microsoft.com/en-us/dotnet/core/install/linux-debian?tabs=dotnet10|Microsoft is publishing .NET installation packages for ARM64 Debian]], there is no need for COMFILE Technology to publish installation packages (e.g. //cpi-dotnet-sdk-9.0//) or for users to install .NET manually. Microsoft's repositories are already added to the operating system so you easily install, update, or remove packages with ''apt''. |
| | |
| | COMFILE Technology has made it easier than ever to develop .NET applications, even WinForms applications, for ARM Linux devices like the Comfile Pi. |
| | |
| | * [[:winforms:index|ComfileTech.WinForms]] - A port of Mono WinForms to .NET 10, maintained by COMFILE Technology. |
| | * [[:comfilepi:dotnet_core_development:remote_debugger:index|.NET Remote Debug Extension for Visual Studio |
| | ]] - Deploy, launch, and debug your .NET applications on the ComfilePi all from withing the Visual Studio development environment. |
| | * [[:comfilepi:dotnet_core_development:vscode_remote_debug_configurator:index|.NET Remote Debug Configurator for Visual Studio Code]] - Easily create the .json files to deploy, launch, and debug your .NET applications on the ComfilePi all from withing the Visual Studio Code development environment. |
| | |
| | Mono is no longer installed by default. Instead, please consider using the [[:winforms:index|ComfileTech.WinForms]] library which will allow you to use the latest version of .NET and C# to write WinForms applications for the ComfilePi. If you would like to use mono, install the //mono-complete// package from the Debian repositories. |

| | ==== chrony ==== |
| |
| | The ComfilePi Trixie OS replaces //systemd-timesyncd// with [[https://chrony-project.org/|chrony]] to provide better support for real-time clock (RTC) control and configuration. |
