If I try to use zdb, it gives ENOENT for whatever dataset I try to use.  Looks
like this:

# zfs list tau/usr/home
NAME           USED  AVAIL     REFER  MOUNTPOINT
tau/usr/home  2.21G   176G     1.05G  /usr/home
# zdb -ddddd tau/usr/home 152278
failed to hold dataset 'tau/usr/home': No such file or directory
zdb: can't open 'tau/usr/home': No such file or directory

Something seems to be terribly wrong here.
