It frequently isn't, and the various Ext3 transition documents out
there generally advise you to reduce the fsck frequency (though not
disable it entirely, just in case). If the system has merely crashed,
fsck will recover the journal (fast) and move on with life. But IMHO
having a working fsck is vital if you have hardware problems and
things die randomly. ext3 gets away with using ext2's fsck, which
means that the tool already exists.
