Perl based product company, that also uses a Perl based product for CMS (WebGUI) and other things.

So, yes I completely understand... we are working a way to make a "Perl Runtime Engine" type of thing to get it out of the hands of the OS to screw it up.

Effectively making a /something/prereqs/{bin|lib|libexec|etc|wth} for "essential runtime" things including MySQL, Perl, Apache, amoung other things.

/something/{appname}/{bin|lib|etc} for the specific applications and data stores...

But again, from a non-dependance on the OS for anything higher than networking/storage/filesystem/(maybe authentication) functions.
