You should always use the absolute paths to invoke commands in any script
run by root.  This prevents people from putting "trojans" in the path
and it will also solve the problem you are experiencing.

for example 
use "/bin/cp" for cp
use "/bin/rm" for rm.

As a practical matter almost no one uses the "only invoke commands by
absolute path" approach.  Its too cumbersome.

But the absolute path approach will fix the problem of invoking aliases
rather than the actual commands.  And it doesn't break when no aliases
are defined.
