Read only filesystem

[nastyhome]

Hi all,

 

I am trying to install Callisto and I stuffed up something in the config file and I need to change it.

 

I stuffed it up that even I cannot go on to both normal and safe mode GUIs.

 

So I booted via single mode -s and I try to edit a file - it says Read only filesystem.

 

What should i do?

 

No - please do not advise me to reinstall

 

Thanks.
