Is the @INC directory for custom Perl modules safe from being overwritten?

(post title should be "dir" not "dire" ) @INC contains the following: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 Which is the safest place to put in-house authored custom modules such that: - generally recognized as being a folder which has been delegated on various systems to contain modules custom to that specific system - no risk of being overwritten/removed by any future cPanel updates
