Hello Guix, Looks like I forgot to describe this patch... It adds the utils package of each used file-system type to the system profile. This behavior can be disabled by setting the “file-system-utils?” field to #f. When you have an issue with your file system it's not the time to discover the absence of the utility package nor trying to install it. This patch fix that. We talked about such feature at[0].
