r328013 introduced a new error code from fsck_ffs that indicates that it could not completely fix the file system and it prints the message PLEASE RERUN FSCK. However, this status can happen when fsck is run in "preen" mode and the rc.d/fsck script does not handle that error code. Modify rc.d/fsck so that if "fsck -p" ("preen") returns the new status code (16) it will run "fsck -y", as it currently does for a status code of 8 (the "standard error exit").
