The `lsblk` program requires root privileges in order to detect file
systems and UUIDs.  I'm guessing your distribution makes it setuid root?

To do the same on Guix System, see the "Setuid programs" section of the
manual.  You would need something along these lines in your config:

 (operating-system
  [...]
  (setuid-programs (cons #~(string-append #$util-linux "/bin/lsblk"))
                         %setuid-programs))

Does that work for you?

'guix refresh -u' only works in combination with the './pre-inst-env'
script, because it tries to modify your Guix directly.

In any case util-linux is already the latest version.
