-    [runnign sync, but sill unclean filesystem at next boot]
-    <slpz> guillem: when libpager syncs an object, it sends an m_o_lock_request
-      and waits (if the synchronous argument was specified) for a
-      m_o_lock_completed. But m_o_lock_completed only means that dirty pages
-      have been sent to the translator, and this one still needs to write them
-      to the backing storage
-    <slpz> guillem: there's no problem if sync() returns before actually
-      writting the changes to disk, but this also happens when shutting down
-      the translator
-    <slpz> guillem: in theory, locking mechanisms in libpager should prevent
-      this from happening by keeping track of write operations, but this seems
-      to fail in some situations
-
-It helps a lot to run [[`syncfs --synchronous /`|hurd/syncfs]] before issuing
-the `halt` or `reboot` command.  This will prevent most of the uncleanliness.
-Of course, [[hurd/translator/ext2fs]] is meant to be doing this to-disk
-synchronization internally upon translator shutdown, but evidently it doesn't
-in all cases.
-
-Apparently diskfs simply does not set filesystems as read-only:
-<http://lists.gnu.org/archive/html/bug-hurd/2011-08/msg00024.html>.
-
-A patch was applied, and the sync issue does not seem to happen any more.
