And that'll last until the first time you transpose two digits in an address 
and clobber the sysres for another system. Or some clever Linux user finds the 
OS data set tools and sets about reading every file you own. 

If it isn't used specifically by a Linux system, it shouldn't be in the LPAR 
IOCDS for that system (unless you have VM mediating access). This isn't z/OS, 
and the "everything everywhere" LPAR definition approach relies on z/OS or VM 
functions to keep you from shooting yourself in the head. Linux doesn't use, 
provide or pay any attention whatsoever to those functions, and it opens up the 
ability to read any data anywhere. 

I'm with Marcy. You can't screw it up if it isn't accessible.
