>Description:
Files which appear as more than one name prevent veriexecctl from loading a signature database successfully as the hash for one of the named files would have already been loaded, such as:
veriexecctl: Cannot load params from `/usr/pkg/bin/perl5.26.0': File exists
This results in veriexecctl reporting that it cannot load /etc/signatures for example.

>How-To-Repeat:
run veriexegen to generate /etc/signatures
try to load the database with veriexecctl load /etc/signatures
>Fix:
