I'm still using an ancient version of veriexec with several mods,
but I think the current version has a state variable you can check.
This would allow you to skip the optimization if veriexec is enabled.
You could perhaps even test if the kernel has any finger-prints loaded for
the mounted fs - if not, then veriexec won't matter - the fs is presumably
being used for data only.
