Are the linux versions of ssisys, rfork, rexecve much like the
UnixWare ones?  If they are you should be able to do a bit better
than printargs.  sys_ssisys is system.c, #ifdef'ed on HAVE_NSCSYS_H.

By the way, the "strace way" of doing this would be to put
"sys_ssisys", "sys_rfork" and so on instead of printargs, and
#define sys_ssisys printargs in dummy.h

I'll have to get around to scrounging up enough hardware to make
myself a Linux SSI cluster soon.
