zramctl

Setup and control zram devices.

Use `mkfs` or `mkswap` to format zram devices to partitions.

• Check if zram is enabled:

lsmod | grep -i zram

• Enable zram with a dynamic number of devices (use `zramctl` to configure devices further):

sudo modprobe zram

• Enable zram with exactly 2 devices:

sudo modprobe zram num_devices={2}

• Find and initialise the next free zram device to a 2 GB virtual drive using LZ4 compression:

sudo zramctl --find --size {2GB} --algorithm {lz4}

• List currently initialised devices:

zramctl
