I would prefer the idea of not snapshotting every directory I do not want to 
include, as there are almost more that I am not interested in. 

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
