Probably not a great idea if you're using btrfs [0].

I wonder if it works [reliably] on ZFS…

Anything that does

  create file
  chmod 0600 file

should be

  umask 077
  create file

Foe the ones, like me, who didn't know why you recommended that:

By setting umask 077 first and then creating the file, the file gets created with the correct restrictive permissions (0600) in one step instead leaving the file readable for "everyone" for a moment.

just buy more RAM, it's cheap enough...

Where do you live ? Must be some magical place where RAM is cheap !

Thank you for your opinion, Bill.

Just kidding, I agree with the sentiment. It's 2026 not 1976. You don't need separate physical partitions for most use cases.
