Since ‘guix-daemon’ runs as root, the ‘guix-daemon’ package¹ assumes
that ~root/.config/guix/current/bin/guix exists.  In fact, the only way
you can install the ‘guix-daemon’ package is by running ‘guix pull’, and
if you run ‘guix-daemon’ you run it as root, so ~root/.config/guix
necessarily exists.

Or could it be that you’re running ‘guix-daemon’ from
~/.config/guix/current as non-root?  That would indeed fail.

In fact it may be enough to do:

  exec ~/.config/guix/current/bin/guix …

instead of:

  exec ~root/.config/guix/current/bin/guix …

in that ‘install’ phase of ‘guix-daemon’.

Thanks,
Ludo’.
