 @end quotation
 
+@item switch-generation
+Switch to an existing system generation.  This action atomically
+switches the system profile to the specified system generation.  It also
+rearranges the system's existing GRUB menu entries.  It makes the menu
+entry for the specified system generation the default, and it moves the
+entries for the other generations to a submenu.  The next time the
+system boots, it will use the specified system generation.
+
+The target generation can be specified explicitly by its generation
+number.  For example, the following invocation would switch to system
+generation 7:
+
+@example
+guix system switch-generation 7
+@end example
+
+The target generation can also be specified relative to the current
+generation with the form @code{+N} or @code{-N}, where @code{+3} means
+``3 generations ahead of the current generation,'' and @code{-1} means
+``1 generation prior to the current generation.''  When specifying a
+negative value such as @code{-1}, you must precede it with @code{--} to
+prevent it from being parsed as an option.  For example:
+
+@example
+guix system switch-generation -- -1
+@end example
+
+Currently, the effect of invoking this action is @emph{only} to switch
+the system profile to an existing generation and rearrange the GRUB menu
+entries.  To actually start using the target system generation, you must
+reboot after running this action.  In the future, it will be updated to
+do the same things as @command{reconfigure}, like activating and
+deactivating services.
+
+This action will fail if the specified generation does not exist.
+
+@item roll-back
+Switch to the preceding system generation.  The next time the system
+boots, it will use the preceding system generation.  This is the inverse
+of @command{reconfigure}, and it is exactly the same as invoking
+@command{switch-generation} with an argument of @code{-1}.
+
+Currently, as with @command{switch-generation}, you must reboot after
+running this action to actually start using the preceding system
+generation.
+
 @item build
 Build the derivation of the operating system, which includes all the
 configuration files and programs needed to boot and run the system.

-From 64ce0ad3731ebd77e02897b07920eadd0e2cc318 Mon Sep 17 00:00:00 2001
-From: Dmitry Janushkevich <gauri@tut.by>
-Date: Mon, 2 May 2016 13:59:26 +0200
-Subject: [PATCH] Fix for issue #282
-
-The fix limits recursion depths when parsing arrays and objects.
-The limit is configurable via the `JSON_PARSER_MAX_DEPTH` setting
-within `jansson_config.h` and is set by default to 2048.
-
-Update the RFC conformance document to note the limit; the RFC
-allows limits to be set by the implementation so nothing has
-actually changed w.r.t. conformance state.
-
-Reported by Gustavo Grieco.
