  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
    • 3. Post Linux-related content
  • Including Unix and BSD.

  • No porn. Even if you watch it on a Linux machine.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.

    I prefer swap files over swap partitions, because it makes it my partition layout simpler to manage.

    If your using a swap partition, make sure it's located on an encrypted partition, else it exposes data stored in RAM (encryption keys etc). With SSD's it's difficult to make sure this data is actually deleted, even after overwriting.

    My preferred setup for a long time was LUKS with btrfs on top. Then subvolumes for /, /home and the swap file (+ /var/cache, /var/log etc.). This gives me peace of mind nothing is unencrypted except /boot.

    Nowadays I simply use zram, which allows for a small part of RAM to be compressed for swap. It's great, simple to setup and performs well. Imo it should be default for all desktops.
