small problem with the init script

[Termalator]

The init script starts with a check if docker is installed, but it always returns that it is installed:
You can fix that with double quotes at "$(which docker)" :

`#!/bin/sh
set -f

log()
{
echo "${1}"
}

log "Checking requirements..."
#if [ -n $(which docker) ]; then
if [ -n "$(which docker)" ]; then
log "> docker => installed"
else
log "> docker => not installed"

exit 1
fi
....`
