Editing the operating system outside of Raspi-LTSP
Although Raspi-LTSP allows you to perform most actions a standard user would need to the Raspbian operating system from within Raspi-LTSP, it is understandable if advanced users may want to directly modify configuration files or install programs on the Raspbian operating system manually.
The key things you need to know are
The Raspbian operating system is stored at
To “chroot” into it (basically allows you to interact with it like a normal Raspberry Pi
sudo ltsp-chroot --arch armhfTo exit when you are finished, just type exit and hit enter.
The lts.conf file (LTSP armhf configuration file) is stored at
To manually compress the operating system for use after a change
ltsp-update-image /opt/ltsp/armhf(this is extremely important you do this after a change!)
The raw boot files before configuration changes have been made can be found at here
An example - Deleting Minecraft Pi edtion
Lets say you want to run a command in the Raspbian operating system, which is stored on the server (and each Pi boots from).
For example, lets say you want to remove Minecraft-Pi edition (which is installed by default).
To do this, open a terminal on the server and enter
sudo ltsp-chroot --arch armhf (
sudo ltsp-chroot also works on its own if you have no other LTSP chroots).
You are now inside the Raspbian OS which is running emulated on the server (via chroot). You can run nearly any command you could run on a Raspberry Pi here, including
apt-get purge minecraft-pi which deletes Minecraft-Pi edition. When you have finished all your changes, enter
exit and you will be returned to a normal server shell.
Finally, you must recompress the operating system! You have 2 options on how to do this.
1. From the commandline with
2. From Raspi-LTSP in the
