BTW, I notice all home dir files and dirs have the same timestamp (2000-01-01 00:00:00). I suppose you do that to reduce the possibility of fingerprinting but I also notice that it applies only to atime (not to ctime and mtime). Might be something you would like to have a look at.
I can apply the same timestamp to the files my scripts add (e.g. touch -r ...). Could you just tell which file is safe to use as a reference (or how do you do this?) I tried to find something in the source code but without success.
You might want to avoid using /tmp folder for executables (if you are doing that, only had a very quick look) as this might one day be no longer possible by default as per Enhanced Security via Mount Options and Compiler Restrictions. Folder /usr/bin would be more suitable.
