That happens if the preen fails.  See the man page I pointed you to.  There
are cases where it can miss things.  You can set:

fsck_y_enable="YES"

If you want it to handle a failed preen automatically.

I don't think background fsck presence or lack of had much to do with
this.  It is a popular whipping boy.

A regular foreground fsck may not be a bad idea if your system is prone
disk errors or hard crashes.  Perhaps sysutils/diskcheckd or a periodic
entry, but under *normal* circumstances such things are not needed.
