>From a usability point of view, there have been many requests
over the years to make FSCKFIX=yes the default. However, from
a safety point of view, this is not fine due to the risk of
unrecoverable data corruption if it does the wrong thing. We
would prefer the admin to take responsibility for any needed
actions prior to fsck (imaging the disc, backups, etc.) and
in some setups e.g. software RAID, it's possible we might
fsck parts of an unreconstructed RAID set and totally destroy
it. There are quite a few other pros and cons, but that's
essentially the reason for it being opt-in; you take the
responsibility for the small chance it might do rather bad
things.
