-- file system files and/or directories. Both are systematic issues we aren't going to make a dent in. The latter being
-- the fundamental issue your administrators should be focused on mitigating; sandbox all apps that could perform hostile IO.
-- If an attacker can write a malicious module or system lib proxy somewhere, you've failed basic attack mitigation,

-- Elevation exploits shouldn't be a problem so long as the linkoptions order is maintained so that $origin and then
-- system libraries are considered before any malcious user-installed libraries could possibly be loaded.

-- you have bigger issues than my 'lets treat POSIX systems more like NT for cross-compatibility and sanity' assumption.

-- of doing things (IE, expecting the user to know how to lockdown vendor supplied packages, RO all LD_LIBRARY_PATHs
-- and other undocumented vendor paths, and do god knows what to harden specific softwares dumped without thought
-- across an arahic FHS/XDG tree, while the developers do jack shit to improve stability, maintainablity, and security).
