[SLE] How to set a reiserfs partition fsck occasionally?

    While the new logging filesystems are a great improvement
     my experience is that they can't survive forever in the real world
     without an occasional rebuild or fsck.

    This list has had warnings by people burnt by reiserfs.
    I haven't (yet) lost any data but have had some scary times.

    This hasn't been bugs in reiserfs (3.6) itself
     as most instability was tracked to (very marginally) flakey RAM.

    However while the glitches were caused by corrupt RAM
     they left me with faults in the filesystem,
     faults that persisted across reboots.

    These included un-list-able and un-cat-able files.
    ie: read or ask the size of that file
     and it's bye-bye to that terminal.
    It made the whole system unuseable
     as processes "trod on the cracks" and hung.
    Backups? Hah, not with that file in the partition.

    So I think a lot of bad press stems from the misconception
     that any filesystem can avoid bitrot forever without an fsck.
    But this is painful to do by hand, I have to boot a rescue system
     and run reiserfsck by hand, to do the root and system partitions.

    How can I get back the old behaviour an fsck happening
     during reboot every x reboots or y days?

    Or, how can I trigger an "fsck reboot"?

    TIA, michaelj

    PS: I've just realized I can do it by adding an fsck
              into the linuxrc script of a cooked initrd image.
            That would give me an "fsck boot" option in grub.
            Comments?
