How remarkably silly of WRS!  I've just checked in usrConfig.c, and it
loads the symbol table by calling netLoadSymTbl() which is only provided
in object format so this can't be changed.

Ah, but there is - you build the symbol table into the vxWorks boot
image file itself.  There's a flag in configAll.h which does this, then
if you use tftp you can say Goodbye to rsh and ftp booting forever!
