Nothing wrong with it, I think that rescuezilla is trying just simplify the process for lesser tech-savvy people. If clonezilla works for you then continue using that.
What do you mean by the project being dead? I just checked, and it had a release in September as well as commits just 6hrs ago, at the time of posting this.
Considering I'm hosting this for family/friends they get rather confused about this when launching a movie and its in Russian.. While its easy to change it would be more convenient if they/me didn't have to. Sometimes movies/shows also strictly only download the movie in Russian even though my settings are applied to only download English stuff.
ah thanks for sharing this :)
