Getting Started

The easiest way to start using and investigating Mere Linux is to download and run the latest Docker image. This of course requires docker running on your system. Alternatively, you can create your own disk image for use in a virtual machine, either locally or in a cloud environment. And if you are able to successfully create your own disk image, then you likely have the skills required to run that image on actual hardware, too.


docker run -it mere/base

Once inside the container, use pacman to investigate and install new packages:

# Update the local pacman database
pacman -Sy

# Query what is installed
pacman -Q

# Upgrade existing packages
pacman -Syu

# Install a new package, for example, a nicer shell
pacman -Sy mksh
exec /bin/mksh -l

Creating a Disk Image

These steps will create a disk image that can be used in a Virtual Machine, like VirtualBox, or in a cloud environment like GCE.


These instructions assume you have set up the development tools as specified in the Development section. If not, please proceed there first, and choose one of the two options.

Prepare a Working Environment

First, create an empty, basic merebuild container:

sudo /mere/bin/lxc-create -t merebuild -n merebuild-dimage

The disk_image script will do the heavy lifting of creating the disk image, so install that to the new container:

sudo install -m0755 scripts/disk_image \

Next, enter into the container with a login shell:

sudo /mere/bin/lxc-start -n merebuild-dimage -F -- \
    /bin/env -i \
    TERM=$TERM \
    http_proxy=${http_proxy} \
    https_proxy=${https_proxy} \
    SHELL=/bin/bash \
    HOME=/root \
    /bin/bash -l

Now, install some required packages:

pacman -Sy --noconfirm e2fsprogs syslinux gptfdisk kpartx

Good! Now you’re ready to create the disk image, which you’ll do inside this container.

Create the Image

First, set a variable to a value of your choice. This will be the root password of the image you create:

export mypass='somekindofpassword'

Optionally, if you want to login over ssh and inspect the system directly, set a variable that controls the installation of the comfort packages:

export comfortable=1

The default disk size used in the following script is 1G. The image can easily be resized later, after creation, but if you would like a different size from the start, specify it:

export disk_size=10G

Create the image by running the disk_image script:


And finally compress the image:

tar -C /tmp -czf /meredisk.tar.gz disk.raw


The new disk image will be located in the container’s root filesystem, so after you exit the container, you’ll probably want to move it somewhere, like: sudo mv /mere/var/lib/lxc/merebuild-dimage/rootfs/meredisk.tar.gz .

The resulting file can be uploaded to Google Cloud and used as a source for a custom disk image there as per the instructions at Or if you unpack the tar archive, you can use the VirtualBox tool VBoxManage to convert the disk.raw file into a format usable by VirtualBox and run the system in a virtual machine there. For example:

VBoxManage convertdd disk.raw newdisk.vdi --format VDI

Resize the Image

If you want to resize the image at any point, take a look at the resize_disk script which can also be run inside a merebuild container.
