Forwarded request:

I want to build DTS for my local network server. It should run a script during system start on the same tty as the DTS menu. How can I achieve that? Just add my scripts to commands.sh and then build DTS?
I just to inject it in /meta-dts/meta-dts-distro/recipes-dts/dts/dts/dts but it's no longer there, I guess the way the menu is created is different now.

It seems like a Yocto recipe adding problem, not a problem related to any servers. Previously we held DTS scripts in meta-dts, that allowed for quick private script injections. Now we use a separate repo for DTS scripts (dasharo/dts-scripts), and therefore the recipe for it has been changed, that made it more difficult to add some private stuff.

There are two ways to handle this issue:

I could help with this exact problem - help to integrate the script. In this case, I need the information, what is the script purpose, what are the dependencies, how it should be installed, etc..

Or I could add recipe integration guide similar to the one from Zarhus.

To keep it as similar as it was previously you could:

1. Fork dts-scripts repo
2. Commit your changes
3. Change SRC_URI and SRCREV to point to your changes

Probably easiest and fastest change. You could even keep your dts-scripts changes locally and use git:///path/to/repo;branch=custom_branch;protocol=file

Another way would be to either add your custom script to meta-dts/meta-dts-distro/recipes-dts/dts-scripts/dts-scripts/custom_script and in do_install inject call to this script with e.g. sed.
You can also inject whole file with sed e.g. sed -i '/^while/r custom_script' dts to inject contents of custom_script into dts after matched pattern in this case it's line starting with while or before matched pattern sed -i '/^while/e cat custom_script' dts (just replace with correct paths in do_install)

[DaniilKl]

Our you can do it inside meta-dts:

1. Create a subdirectory under dts-scripts directory and add your script:

λ mkdir meta-dts-distro/recipes-dts/dts-scripts/dts-scripts
λ vim meta-dts-distro/recipes-dts/dts-scripts/dts-scripts/your-script.sh

2. Modify recipe for dts-scripts so it will install your script:

3. Build DTS.

@wessel-novacustom check whether these guides will help you.

[m-iwanicki]

@DaniilKl mention that your way won't run a script during system start

I see I missed that part, yep, my guide only for adding script into FS, not for running it on start up.

• That's vital for us, though. Could you please implement such function and provide a test version?

[DaniilKl]

@wessel-novacustom, I could do that. But I need some information:

1. What the script will do?
2. What are the dependencies for the script?
3. At what moment you want to start your script?

• After boot, right before the DTS menu opens.

I need to build DTS myself and it should check if autostart.sh in whatever folder is available. I should be able to include the autostart.sh in a folder that you specify. You can test it with something like echo Hello world! && pause 10 to check if it is working correctly.

In case it autostart.sh is available, it should execute that script. Otherwise, it should open the DTS main menu as usual.

I should fill the contents of autostart.sh myself as I would like to have that in my own control.

[DaniilKl]

@wessel-novacustom, you cold do the following:

1. Fork Dasharo/dts-scripts (this is the place where all DTS scripts are located now) and clone it.
2. Do the following modification:

3. Add your autostart.sh into the cloned dts-scripts repo root.
4. Commit and push the changes to your fork.
5. Change dts-scripts_git.bb in meta-dts to point to your fork and your changes:

Where: PROTOCOL is either http or ssh, BRANCH is the branch you pushed your changes to, COMMIT is a hash of the commit that contains your changes.

6. Build:

kas-container build meta-dts/kas.yml

Note, if you used ssh protocol in the recipe, you should provide your keys to build, e. g.:

kas-container --ssh-dir ~/.ssh build meta-dts/kas.yml

@DaniilKl Thank you so much! I will try in January and let you know if it worked.

[wessel-novacustom]

@DaniilKl The script is correctly executed at the background, thank you.

I'm working around that the scripts runs at the background by using:

broadcast_to_tty() {
    local message="$1"
    echo "$message" > /dev/pts/0 || echo "$message" > /dev/tty1
}

That works, but another problem is that the V540TU doesn't have internet access with the latest DTS version, even if the original DTS version is booted. This wasn't a problem when using v2.0.0-rc3 ... I hope this can be fixed soon :-)
