I used netinstall-cli with -s userscript to send a configuration to a rb4011 along with the firmware. I did not expect that it would save that script in /system/default-configuration/custom-script, and will always use it when the reset button is used, which is actually a nice feature. However, it seems that it also uses it when /system/reset-configuration is used and I don't see a way to get back to defconf. I even tried netinstall-cli with no -s and it still used the saved config as default config.
How can I remove the saved custom-script?
