foo.c:18: error: syntax error before '"'
foo.c:18: error: stray '\' in program
foo.c:18: error: stray '\' in program

vsystem("echo '# Note that BSD'\"'\"'s export syntax is \"host-centric\" vs. Sun'\"'\"'s \"FS-centric\" one.' >> /tmp/exports");
is what it takes to make this work.

NOW! we have a winner.

Below is the test program.  Which form should we go with?

#include <stdio.h>
#include <stdarg.h>
#include <unistd.h>
void vsystem(char *fmt, ...)
{
    char cmd[500];
    va_list args;
    va_start(args, fmt);
    vsnprintf(cmd, sizeof cmd, fmt, args);
    va_end(args);
	execl("/bin/sh", "/bin/sh", "-c", cmd, (char *)NULL);
}
int main() {
//vsystem("echo '# Note that BSD'\\''s export syntax is \"host-centric\" vs. Sun'\\''s \"FS-centric\" one.' >> /tmp/exports");
//vsystem("echo '# Note that BSD'\"'\"'s export syntax is \"host-centric\" vs. Sun'\"'\"'s \"FS-centric\" one.' >> /tmp/exports");
return 0;
