I was aware I could use brute force to change it but its always nice to put everything back as it was - nothing more annoying that your system going wobbly because someone's put in sensible users for security reasons and you go and stop them writing by accidentally leaving something owned by root
cp -a file file.backup
vi file
..check new file and backup - to revert:
mv file.backup file
And note that vi (and vim) try very hard to preserve ownership and file
modes, so if you edit a users file with vi as root, it will be re-written
with the same user and file ownerships as before.
