But on any platform you would use Roadshow 68k on, it clearly is not part of the OS, and that much is obvious! The least you could do is to give the user options, to carpet bomb sys: with files and directories, or a more conservative approach.
Of course, and I had to manually move things after the initial jaw dropping experience.
Noone expect that to work, hehe.
I think you're blowing it out of all proportion here. There really isn't that many files, seriously. They're not scattered here there and everywhere either.
I'm very strict upon which installs scripts I allow to run on my Amiga, and I have no problem at all with Roadshow in this regard.
