"Working with root is either great fun or extremely dangerous,
depending on how much you like the feeling of supreme executive
power.
"But if you're one of the people who fears the mighty power of
the superuser to delete files with impunity, what you need is
chattr: it lets you set a file as being immutable, which means that
not even root can delete it. For example: running chattr +i
myfile.txt as root will make that file virtually indestructable no
matter what user you are. If you want to remove the shield of
steel, use -i rather than +i."
