Systemd zRAM service

--------------------

Use a part of your RAM as compressed swap.

[`zram`](https://en.wikipedia.org/wiki/Zram) is a Linux kernel feature

that provides a form of virtual memory compression. `zram` module increases

performance by avoiding paging to disk and using a compressed block device in

RAM instead, inside which paging takes place until it is necessary to use the

swap space on a hard disk drive. Since using `zram` is an alternative way to

provide swapping on RAM, `zram` allows Linux to make a better use of RAM when

swapping/paging is required, especially on older computers with less RAM

installed.

This program provides a systemd service to automatically load and configure

such module at system boot.

You can choose compression algorithm by editing systemd service. To see available 

algorithms do `cat /sys/block/zram0/comp_algorithm`.

Installation

------------

You can choose between different installation methods. Note that uninstallation

don't removes active zram disk.

### Classic method ###

- Build and install:

        $ make

        # make install

- Uninstall:

        # make uninstall

### Debian package ###

- Build and install:

        $ make debian_pkg

        # dpkg -i systemd-zram_*.deb

- Uninstall:

        # apt purge systemd-zram

### Arch Linux package

- Build and install:

        $ make arch_pkg

        # pacman -U systemd-zram-*.pkg.tar.xz

Alternatively you can install it from AUR:

        $ trizen -S systemd-zram

- Uninstall:

        # pacman -Rsc systemd-zram

Usage

-----

To start the service execute as root:

        # systemctl start systemd-zram

To stop it:

        # systemctl stop systemd-zram

If you want to enable zram at boot, just run as root:

        # systemctl enable systemd-zram

And for disable it at boot:

        # systemctl disable systemd-zram
