Firstly, I am glad someone saw threough my poorly worded question what I meant - I _am_ looking for your definition of atomic - "do it, or don't do it - don't go halfway..." Well the two main places of concern are the permissions script and the rsync - if something goes wrong with either it could be a BadThing(tm).

I like your idea of the undo() function, but am not sure it would be feasible in either case, meaning I am not sure if there would be a way to actually undo what had occurred. One way I might be able to cover myself on the rsync is to first run the rsync with the --dry-run option, and as long as all goes well run it without. Is there any kind of "dry run" in perl? Does eval or try work in that way - in that it tries to do it, but doesn't actually do it unless it is sucessful?
