The overlay on /etc/ is managed by SteamOS Offload (package steamos-customizations), not by Rwfus. You can only have one overlay mounted per directory, and they've already taken it.

Disabling their overlay would wreak havoc on anything that's currently running.

Your /var/ partition is completely full. You might want to track down what's eating so much space with du -h /{var,etc}/*

[aemonge]

Is that why sudo rwfus -t returns:

Rwfus is not installed. Install it with `rwfus --install`

For what I'm undesrtanding from you, the overlay for /etc it isn't related, right?

I've tried cleaning out the /etc and /var directories, but they filled up by regular txt files. Though I think this part (the overlay) isn't related to the install

[ValShaped]

Rwfus -t runs the Rwfus configurator in test mode, which is pretty much a dry-run mode.

The /etc/ overlay isn't Rwfus, yes. It's handled by SteamOS and there's nothing Rwfus can do about it, because Rwfus relies on /etc/ to install itself.

What text files are you referring to?

[aemonge]

Ohh, then it is a miss understanding from my part. I though rwfus -t would check if the installation is correct.

I've re-installed Steam OS and the first thing I've done is running rwfus and have avoided steamos-readonly disable entirely, and now it's working as expected with a right size for the overlay too :)

I think, people should be warned not to steamos-readonly disable if they'll be working with rwfus :)

[ValShaped]

There are situations where rwfus can be viable as an alternative to steamos-readonly disable (as that's why I wrote rwfus in the first place) and others where steamos-devmode enable (which implies steamos-readonly disable) is critically necessary to not end up with an unbootable system.
