This first time I have ever work with Promox. The installation is very easy and quick. But I am a big fan of ZFS for lots of good reason. I am former Sun Engineer. Been working with Sun since 1985. I am not surprised your supporting ZFS but I am surprised you are not allowing users to decide the type of Filesystem to put on as a boot disk. It be a lot easier and less painful should you at least allow that during installation. You certainly done a great job on the GUI interface and certainly kept the convention there. I am sure the decision to use Debian over many other linux distro, would been nicer to seen it on Solaris x86 which nowdays has ZFS built-in. Along with a lot of cool network capabilities. This will take a little getting used to but like what I see so far.
