+Optimize the store by hard-linking identical files---this is

+The daemon performs deduplication after each successful build or archive
+import, unless it was started with @code{--disable-deduplication}
+(@pxref{Invoking guix-daemon, @code{--disable-deduplication}}). Thus,

@item --list-dead
Show the list of dead files and directories still present in the
store---i.e., files and directories no longer reachable from any root.
