For changing config files in Venus OS I found the hint on Github:

> Since the root filesystem is mounted read-only, you will need to remount it to read-write before you can edit the file. There are three ways to change that:
> 
> - _temporally_: issue the command `mount -o remount,rw /` (which holds until the next reboot or issueing `mount -o remount,ro /`)
> - _semi-permanent_: issue the command `/opt/victronenergy/swupdate-scripts/remount-rw.sh` (which holds until the next firmware update)

Maybe it is relevant..?

That is because you are not posting as a code block...

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote `````)

````auto
``` 
   code goes here 
```

````

You can edit and correct your post by clicking the pencil ✏ icon.

It locks up on selecting code quotes.

Reopened this page so many times now that I've inadvertantly edited this post !

Safari? Old version of Chrome? Internet Explorer?

You really dont include enough info in your posts to properly help you ☹

Also, you can simply type in the three backticks ````` using your keyboard (or even copy paste these backticks from my post)

Edit: It's opera

I didn't know you could just type the backticks...

Weird...just typed the backticks and it locked up again.
