I see this unresolved > issue from earlier versions remains. A program is a file on disk. A process is a running memory image. Neither fork() nor exec() cause the tunables to be loaded, the process itself has to do that. For dynamic ELF programs/processes built with glibc, ld.so does it before it passes control to the ELF image. There are other types of programs/processes that do not use ld.so and thus do not read the tunables cache (which is called "ld.so.cache" for a reason ;-) I don't know how to say this clearly with fewer words... >> +The syntax allows lines to start with the keyword >> +.I include > > s/I/B/ (since it's a literal, not a variable) Fixed.
