[Rpm-maint] odd chroot behavior inside the rpm transaction

[Seth Vidal]

https://bugzilla.redhat.com/show_bug.cgi?id=503195#c13

as I said:
  if, from the python bindings, I open a file with a name starting with '/' 
while in a transaction then as expected, the file is opened inside the 
installroot

however, if I open a file with a name NOT starting with '/' then the file 
is opened OUTSIDE of the installroot.

Does this make any sense? B/c I admit I don't quite grok why it would be 
this way.

Thanks,
