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. -- Adam
