That philosophy also has some drawbacks:
- The user doesn't directly that anything went wrong. Thus errors may
even continue to accumulate and getting much worse if the fs would have
immediately gone ro and giving the user the chance to manually
intervene (possibly then with help from upstream).
- Any smart auto-magical™ repair may also just fail (and make things
worse, as the current --repair e.g. may). Not performing such auto-
repair, gives the user at least the possible chance to make a bitwise
copy of the whole fs, before trying any rescue operations.
This wouldn't be the case, if the user never noticed that something
happen, and the fs tries to repair things right at mounting.
So I think any such auto-repair should be used with extreme caution and
only in those cases where one is absolutely a 100% sure that the action
will help and just do good.
Cheers,
Chris.
