-Guix System allows rebooting into a previous generation should the last
-one be malfunctioning, which makes it quite robust against being broken
-irreversibly.  This feature depends on GRUB being correctly functioning

-becomes corrupted during a system reconfiguration, you may not be able
-to easily boot into a previous generation.  A technique that can be used
-in this case is to @i{chroot} into your broken system and reconfigure it
-from there.  Such technique is explained below.
