Stop making swap partitions–use swap files instead

9 hours ago

Swap files have performed as well as swap partitions for over 20 years, but many Linux distributions still promote swap partitions during installation.
Swap files are more user-friendly than swap partitions, allowing easier addition, removal, modification, and extension after setup.
To set up a swap file, use `fallocate` to create it, set proper permissions with `chmod`, format it with `mkswap`, enable it with `swapon`, and add it to `/etc/fstab` for persistence.
For Btrfs filesystems, refer to specific documentation to ensure swap file compatibility and proper configuration.
