Paul,
Fair enough, though "kernel" has a specific meaning, the stuff that runs in

Preface chapter:
"The words "system" or "VMS system" are used to describe the
entire software package that is a part of a VAX-11 system, including privileged processes,

The word "executive" refers to those parts of the VMS operating system that
reside in system virtual address space.
The executive includes the contents of the file SYS.EXE, device drivers, and other code
and data structures
loaded at initialization time, including RMS and the system message file. "
