root

I have a VPS, until now I used the default root user for SSH access and everything. For security reasons I'd like to use a different user for root, terminal access and sudo operations. So I created another user, gave him the sudo and every other perm.

The problem is that all the system files belongs to root. What happens if I set PermitRootLogin No for root? Those files wouldn't be editable by the new root user!
