Another data point.
I just ran through my test case, saving the tagged and transcoded
files into /tmp, a zfs filesystem that was created back when I built
up the system (contemporaneously with /usr/home). I was unable to
trigger the bug there.
As I control, I then ran through the test case, saving a directory in
my home directory and triggered the bug.
I then created a new directory /usr/home/foo (within the same zfs
filesystem as my home directory). I was unable to trigger the bug
there either.
I then ran through all 165 flac files in the full "test case", saving
the results to /usr/home/foo. After exiting picard and running flac
-t on all of the files I had errors on many files, including the file
in my single-file test case above. I did not even need to reboot.
I then ran the single file test case, saving into /usr/foo (as above)
and was now able to observe the error after a reboot.
I then ran the single file test case (again to make sure I wasn't
crazy), saving into /usr/foo (as above) and was now able to observe
the error after a reboot.
One more control.
Create /usr/home/bar.
Run single file test case. Reboot. This time I observed an invalid
flac. Not sure what this means about the test case above.
Sigh.
