systemd_zram:
  # /etc/systemd/zram-generator.conf.d/zram0.conf
  - name: zram0
    options:
      # The size of the zram device in MiB
      zram_size: "256"
      # Compression algorithm: lzo, lz4, zstd, lzo-rle
      compression_algorithm: lz4

systemd_zram_cleanup

When true, remove all existing configuration files before creating the new ones.

# Default
systemd_zram_cleanup: false
