Nobody expected you to. We're trying to figure out any commonalities
that might exist; these may serve to help shed light on where the
The interesting thing is that I took it and looked at it and came to a
conclusion that might have been wrong, though I think the trail of
reasoning I used was itself reasonable, given my exceedingly small (one
example of problem) sample size.
Mark's able to actually *reproduce* the problem on separate installs
and with circumstances that are at least somewhat different than what
my theory involved, though it is not quite possible to rule out some
sort of corruption.
Since I have to *assume* that many sites run some sort of FreeBSD on
their VMware gear, given that VMware actually lists it as a supported
version and VMware generally does things "for profit", I am still kind
of of the opinion that this is some sort of corruption bug, one that I
triggered inadvertently, but one that Mark's environment reproduces
rather more frequently. That just seems so unlikely, but more unlikely
things have come to pass, so I'm holding onto it as my working theory ;-)
I still plan to try to recover my broken VM from backups at some point
if time permits.
But in short, to answer your question: I don't *care* if you can
reproduce the problem. As a user, you can't win. If you don't report
a problem, you get criticized. If you report a problem but can't figure
out how to reproduce it, you get criticized. If you can reproduce it
but you don't submit a workaround, you get criticized. If you submit a
workaround but you don't submit a patch, you get criticized. If you
submit a patch but it's not in the preferred format, you get criticized.
