I think we all know where we are headed

It is not age verification

It could be used as part of a age verification system but it isn’t by itself age verification. You are doing the equivalent of calling a set of tires a car.

All of this was discussed in the PR.

Systemd is present on the vast majority of Linix systems so it made the most sense to put it in systemd. It is an optional field so it is up to applications and distros on weither to use it for something. Age verification laws are legally binding so compliance is not optional.

If you have a problem with age verification call your local lawmaker. Don’t attack a bunch of devs who somehow got stuck in the middle.

For better or for worse ZFS does what it does really well. Right now we don’t have much in the way options.

You technically can but the btrfs implementation is problematic. It has gotten better but it isn’t remotely production ready.

It does support raid1, raid10 and raid1c2/3. The reason I like btrfs is that it is baked into the Linux kernel so I can manage it with the file system utilities. It also runs well on cheap mismatched hardware it I don’t need to spend a fortune on storage.

It depends on what you are doing

Doubt

If anything btrfs is a decent replacement for ZFS
