      Patches of new test profiles/scripts always welcome for inclusion.

        don't give physical access to adversaries
        or encrypt swap
        or don't use swap

          But... reflink with XFS is stable or not?

            It is on Btrfs. It works great.
            I use alias cp='cp --reflink=auto' in my bash profile.

              Of course, I use it with snapshots too, but I'm interested in XFS implementation, some month ago I red that reflink was in beta for XFS

                I wonder what would be the results for ext4 after my usual tuning: noatime,nobarriers,data=writeback.
                On the other hand, these optimizations mostly affect write performance, so read performance perhaps will remain the same?

                  Me too. My laptop and other PC are unencrypted.

When I was using adsl, I had 100 attackers per day to my router firewall, with 3G/4G mobile networks zero.
                    Even modern countries still offer ADSL. Here in my country, it's still the second most used internet access technology (or whatever you call it) besides Fiber. And I do live in a modern, Western European country.

                      Is that safe to apply on SSD's? My SSD is modern (this is a 2018 laptop).
