I watched someone save a buffer from emacs into apparent oblivion.
Somehow or another, the super-block did not update. The file looked
like it was there when you did an "ls -als" but when you tried to cat
the file, it was not there. Syncing remidied the situation.
1) I too have been bitten by this bug. Are there others out there? (I
suspect yes)
Do they have the perspicacity to try syncing when they loose like this?
(I doubt it)
2) Why does this happen?
3) What would have happened if the user had logged out and logged back
in again? Would the file have reappeared, would it have disappeared
completely, or would it still be around the next time the super-block
gets updated?
As a side problem, the /usr/tmp/auto-save-file somehow gets wedged and
only auto-saves once.
