rrdtool performs as expected:
-bash-2.05b$ /usr/local/rrdtool-1.2.10/bin/rrdtool create /foo.rrd DS:sec:GAUGE:600:0:U RRA:AVERAGE:0.5:1:576 ERROR: creating '/foo.rrd': Permission denied
Thanks, Larry Barber

No joy, it is still crashing, stack trace:
Does rrdtool work for you? Try running rrdtool create /foo.rrd DS:sec:GAUGE:600:0:U RRA:AVERAGE:0.5:1:576 Assuming you're not root, this should print out the message ERROR: creating '/foo.rrd': Permission denied
I was looking at your patch, and it doesn't look to me like that new lines are doing the same thing as the old:
strcat(filedir, "/"); strcat(filedir, fn);
snprintf(filedir, sizeof(filedir)-1, "%s/%s/%s", rrddir, hostname,filedir[sizeof(filedir)-1] = '\0'; creparams[1] = filedir; /* Icky */It looks like the original line creates something like "filedir/fn" while the new lines create something like "filedir/hostname/fn". Is this right?
It is. In the old version, "filedir" contained the rrd top-level directory + the hostname, e.g. "/hobbit/rrd/myhost", and then it added an extra "/" and the rrd filename.
The new version just uses snprintf() to output the top-level directory + the hostname-directory + the rrd filename in one go.
sprintf(filedir, "%s/%s", rrddir, hostname); if (stat(filedir, &st) == -1) { ... } snprintf(filedir, sizeof(filedir)-1, "%s/%s/%s", rrddir, hostname,fn); filedir[sizeof(filedir)-1] = '\0';
