The error

@Misekayek0l Use;


# combustion: network
exec > >(exec tee -a /dev/tty0) 2>&1

Not #!/usr/bin/env sh

Whit is the exec thing?

@Misekayek0l first line is for the network, second copy the output to the tty.

Changed #!/usr/bin/env sh to #!/bin/bash and the error persists

And the other part for network?

What it is?

It will no terminate my script unless is in the end?

@Misekayek0l you need to have # combustion: network for the network to function. Yes, it will run the script and move on to finalize the install…

It worked. By the way how do make it to reboot to apply the kernel changes

@Misekayek0l not sure, but systemctl reboot should suffice.

But It would no longer execute the network bit or would not even be executed. (In the combustion script)

@Misekayek0l add a reboot service to run once after finished.

After which service it should run?


Description=First Boot Reboot

ExecStart=rm /etc/systemd/system/firstbootreboot.service
ExecStart=rm /etc/systemd/system/
ExecStart=systemctl reboot


Add to combustion script

## Reboot after setup
cp firstbootreboot.service /etc/systemd/system/
systemctl enable firstbootreboot.service

Now I am missing the kubeadm command

@Misekayek0l so in the output do you see it all (as in packages) getting installed? I normally do one zypper -vvv in ... command…

Where is the combustion output?

Found it, get here Combustion script fails to install kubernetes - #6 by Misekayek0l

Looks like my script needs network in an early stage of execution, thus I need another solution for network
