The ComfilePi Trixie OS is derived from the Raspberry Pi's Trixie OS, which itself is derived from Debian's Trixie OS.

The ComfilePi Trixie OS introduces several significant changes to prior OS releases – some introduced by upstream Debian and Raspberry Pi, and some introduced by COMFILE Technology.

If you have an existing solution currently deployed prior OS variants, it is recommended that you do not upgrade to Trixie unless you have a compelling reason to do so. If you are embarking on a new solution, it is recommended that you do upgrade to Trixie.

See the Debian Trixie release notes.

See the Raspberry Pi Trixie OS announcement.

After provisioning your ComfilePi with your customizations, it is highly recommended to enable the read-only file system.

• It protects the bootfs and rootfs file systems from corruption.
• It increases the longevity of the storage device's flash memory.
• It provides the ability to withstand an abrupt loss of power without requiring shutdown.

Due to several bugs in the Raspberry Pi read-only file system overlay, for Trixie, we have chosen to mount the file system read-only instead of using an overlay. Like Bookworm, this can be easily enabled via a GUI.

Or, use the following commands:

Enable the read-only file system

sudo cpi-make-readonly
sudo reboot

Disable the read-only file system

sudo cpi-make-readwrite
sudo reboot
