Hmm, right. We could keep a list of all files that need fsyncing, and then fsync them all just before writing the checkpoint. Half of that is already done (for the content of the packages), we would need to add it for the files in /var/lib/dpkg/, or we could just fsync the whole directory. But then again, I would argue that the sync() is actually necessary always, for correct semantics: You also want to sync everything that the postinst script has done before recording that a package is fully installed. -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
