[blink] that would certainly have saved me some time. It was my
understanding that the CDDL-licensed ZFS couldn't be placed into Debain, but
clearly I was mistaken.

I hadn't known that, Paul. Thanks. If nothing else, I want to develop and
maintain the techniques necessary to build such installation media up.
There's also a flash-updating udeb I'm including for use with LSI SAS2008
controllers; perhaps I ought make a mainline deb.

of course.

I would in this case rather file the bug against GCC, actually.

I would be very interested in doing so. I've created the username nickblack
on the mentors server. If you'd be interested in mentoring me, please
respond privately.

It's been our experience that oprofile storing results in a tmpfs or SSD
introduces such low overhead that development environments ought just always
have it running in a sensible default configuration, with variously merged
outputs only a command away. If ident-level oprofiling data was as easily
available as top, we feel, programmers would be much better informed.
It is possible that linux's "perf" tool is better adapted to this task.
