Having just experimented with Babun over the weekend... the package manager is a pretty big deal. It used to be that you had to re-run the Cygwin installer whenever you wanted to add a package. That&#x27;s just silly.<p>Outside of that, the biggest difference is it avoids Cygwin&#x27;s complicated setup process. You run the installer script, it creates a ~&#x2F;.babun directory, and then it just works. No need to commit to a list of packages at install time. It gives you a very reasonable set of defaults, and if you need more, you just &quot;pact install&quot; it.<p>Supposedly it has a self-update mechanism that will take care of Cygwin updates. I haven&#x27;t had it installed long enough to see it in action.<p>And no, they don&#x27;t explain what BLOADA is. :) It&#x27;s also a little tricky to run rebaseall, since the rebaseall tool doesn&#x27;t like zsh running. (The workaround, btw: &quot;cygstart dash&quot;, then proceed with rebaseall.)
