This @code{~/.config/guix/current} profile works like any other profile
created by @command{guix package} (@pxref{Invoking guix package}). That
is, you can list generations, roll back to the previous
generation---i.e., the previous Guix---and so on:

+@subsection Building the Installation Image for ARM Boards

+Many ARM boards require a specific variant of the
+@uref{http://www.denx.de/wiki/U-Boot/, U-Boot} bootloader.
+
+If you build a disk image and the bootloader is not available otherwise
+(on another boot drive etc), it's advisable to build an image that
+includes the bootloader, specifically:
