To prevent the above from happening, use a MAC or a RBAC system such

You should also be able to use file flags such as undeletable and
immutable together with higher security levels (at least under BSD) to
prevent root to remove/change the file under normal run-levels. 

(Normal run-levels excludes single-user mode and stunts like mounting
the drive in non-native environments.)
