That's why I have terribly outdated 13-CURRENT on bunch of servers and can't
update them. 

Most of them look like this:
[tiger_at_st25]:~>zpool status
  pool: st25
 state: ONLINE
  scan: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        st25       ONLINE       0     0     0
          mirror-0  ONLINE       0     0     0
            ada0    ONLINE       0     0     0
            ada1    ONLINE       0     0     0
          mirror-1  ONLINE       0     0     0

errors: No known data errors

They haven't separate boot device and have from 7 to 30+ Tb of data that I
can't backup anywhere for re-install server with disk partitioning. Some time
ago I managed to get aroud this reverting 2 commits (  r342151 + don't
remember revision) but then there where some other improvements after which I
lost the opportunity to revert this commits
