writes, resulting in the need for the fsck at every boot. Then a
couple of professors wrote a paper detailing how ordered writes
could fix file system corruption problems. This is now
incorporated in the modern FFS. File system check is now only
needed to recover lost disk space, and no longer needs to run at
every boot (so could be turned off). 0 seconds is faster than 10
seconds, and a journal is not required. However now that disks
are caching data, data loss could occur. I always turn off the
disc cache to avoid this (which slows down disk writes). Note
that ext3 only journals the meta data, so if a journal is also
required for data (otherwise why journal at all?) then something
like our LFS would be needed.
