Description of problem:

  27 if [ $UID != 0 ]; then
  28     error "mkinitrd must be run as root."
  29     exit 1
  30 fi

This happens within the very first lines of the mkinitrd script, prior to
"error" function being defined, which results in something like this:

$ mkinitrd
/sbin/mkinitrd: line 28: error: command not found
$
