 /etc/rc.d/fsck_root invoked "fsck -p /" (assuming that fsck_flags had
 the default value of "-p").  Given that, it's not clear to me that fsck
 should have behaved any differently.  (It is clear that the fsck_root
 script should not have invoked fsck, but that falls under your point 2
 below.)

 Yes, a missing fs_passno in /etc/fstab should behave like fs_passno-0,
 and should prevent the fsck_root script from trying to fsck the root
 file system.  I see you fixed that already.
