It seems that disabling it should simply be safe. But re-enabling, one risks losing tags, as the next notmuch new will cause old maildir flags to override the xapian database. So that suggests something like: notmuch dump > backup notmuch config set maildir.synchronize_flags false # Do I need to run notmuch new here? notmuch restore < backup Is that safe? The man page suggests one additionally need to run notmuch new before running notmuch restore. All of this is pretty slow. Is there a more efficient way? A one or two sentence clarification in the notmuch-config man page might be helpful to people contemplating playing with this switch. The default is on, to I suspect it costs a lot of performance. I've been afraid to turn it off for fear that I won't be able to undo this cleanly. Thanks, David
