I have an embedded linux environment which has a read only root file system on it. I am unable to edit files and create new directory in the read only root file system as expected.
However, I see that I am still able to change the contents of file
How is that possible? This actually works out for me. But I was just wondering why am I able to edit it?
Edit1: I am even able to create a write into
Edit 2: So I see that
resolv.conf -> /etc/resolv-conf.systemd
resolv-conf.systemd -> ../run/systemd/resolve/resolv.conf
