My question would simply be: Does the method going over the writeable snapshot and deleting things always lead to the same incremental end result as marking directories as snapshots that I am not interested in (apart from the additional empty directories created in case of the latter)? Furthermore hidden directories in home change very often, meaning if I install additional software, additional hidden directories may be created. So my script would have to mark them as snapshots every time. If I have hidden files, I cannot mark files as snapshots, so it is clear that my method makes sense. Once I have marked these directories snapshots and I want to create snapshots of my whole home subvolume I would always additionally have to specify those. So it makes the whole situation less manageable. Apart from that I find marking every directory I am not interested in as snapshots highly inelegant. So my question would be, if my preferred method is as reliable as the suggested method. Hope that's on the mailing list now :-). Thanks
