DirectAdmin automatic updates

After a somewhat nice series on DirectAdmin earlier, i wanted to make a small addition to it: automatic updates. It’s a bit of a no-brainer to say that you should keep your system up-to-date. The only real debate here is: should you perform these  automatically of just check every week and perform them manually. I’ve…
