The toy, the toy specialised for each of frr, BIRD, Suricata, BIND and Asterisk, the bundle, the sources with the store they compile from, and four directories of guest images to put in /var/lib/cloonix/bulk.

Cloonix

`cloonix-toy.tar.xz`	23 MB, 111 MB extracted. cloonix inside its own container. No root, nothing installed: extract, `./setup.sh nemo`, `./nemocmd start`. The images go in `/var/lib/cloonix/bulk` before `./setup.sh`: a bulk made after it is not seen by the toy. Get started uses this one.
`cloonix-bundle.tar.gz`	35 MB. The compiled run-time for a machine several people share. Installed once as root by `sudo ./install_cloonfs`, under `/usr/libexec/cloonix`.
`cloonix-source-102.tar.gz`	the source tree: cloonix, the demos, the image builders of `vm_create`, the tests, the two books. The same tree as github.com/clownix/cloonix; `./doitall` at its root builds the bundle, `toy_targz/create_toy_targz.sh` the toy, `toy_targz/create_<name>_toy_targz.sh` the specialised toys; `build_tools/vmbuild/doitall.sh` makes all of them in a builder machine.
`cloonix-targz_store-102.tar.gz`	goes with the sources, and is needed before anything compiles: the open sources cloonix rebuilds, qemu, open vswitch, crun, passt and patchelf, each at the commit this version was made with, and the base root file-system. Extracted at the root of the source tree it is the `targz_store` directory, which `./doitall` reads instead of the internet.

The toy, specialised for one project

The same toy, for one open source project, containers only: no kvm, and the project installed in the root of the toy itself, which its containers run on as self_rootfs, so nothing else is to fetch. Only its demos, among them the examples of its own documentation. Each one is used like the toy: extract, ./setup.sh nemo, ./nemocmd start, then the Demo button of the canvas. Any other container image goes in /var/lib/cloonix/bulk before ./setup.sh: a bulk made after it is not seen by the toy. Of the image of its project, such a toy takes the commands its demos run, the packages they need and the libraries of both, nothing else: frr without python, BIRD and Suricata with only the python modules their demos import, and BIND without python.

`cloonix-frr-toy.tar.xz`	frr, from the `frr_trixie` image: the three demos of `routing/` (frrspider, frrspider_bgp, frrmix) and, in `frr_demo/`, 26 examples of the FRR User Guide, segment routing, SR-TE driven by the Pola PCE and L3VPN over SR-MPLS and SRv6 among them.
`cloonix-bird-toy.tar.xz`	BIRD, from the `bird_trixie` image: the demo of `routing/` (bird) and, in `bird_demo/`, 13 examples of the BIRD User's Guide.
`cloonix-suricata-toy.tar.xz`	Suricata, from the `suricata_trixie` image: the demo of `security/` (suricata) and, in `suricata_demo/`, 7 examples of the Suricata User Guide, the sensor as a router or inline as an IPS.
`cloonix-bind-toy.tar.xz`	BIND 9, from the `dns_trixie` image: the demo of `address/` (dns) and, in `bind_demo/`, 12 examples of the BIND 9 Administrator Reference Manual, from a primary and its secondary to a resolver walking a lab internet from its root, DNSSEC, catalog zones and a DNS firewall.
`cloonix-asterisk-toy.tar.xz`	Asterisk, from the `asterisk_trixie` image: the demo of `services/` (asterisk) and, in `asterisk_demo/`, 14 demos of the Asterisk documentation with baresip phones, SIPp and Kamailio, from a first registered call to TLS and SRTP, NAT, voicemail, conferences, queues, IAX2, load tests and a load-balancing proxy.

To compile, the two together:

wget https://clownix.net/downloads/cloonix-source-102.tar.gz
wget https://clownix.net/downloads/cloonix-targz_store-102.tar.gz
tar xf cloonix-source-102.tar.gz
cd cloonix-source-102
tar xf ../cloonix-targz_store-102.tar.gz
./doitall

The build runs inside a debian trixie machine made by build_tools/vmbuild/doitall.sh; the chapter on building of the documentation has the steps. To run cloonix and not compile it, the toy alone:

wget https://clownix.net/downloads/cloonix-toy.tar.xz
tar xf cloonix-toy.tar.xz

Guest images

A guest needs an image in /var/lib/cloonix/bulk, the same directory for the bundle and for the toy. The four directories below hold what vm_create/allbulk.sh of the source tree builds, from a local mirror of each distribution, without root.

A container image: `.tar.gz`

Copied into bulk as it is. The first add cnt on it extracts it once, into <image>_targz, for every network and every user of the machine.

cd /var/lib/cloonix/bulk
wget https://clownix.net/downloads/cnt_bulk/trixie.tar.gz
cloonix cli nemo add cnt c1 eth=1 trixie

The extracted tree is never modified and takes no --persistent. For an image to change, extract it under another name: mkdir mytrixie && tar xpf trixie.tar.gz -C mytrixie.

A machine image: `.qcow2.gz`

Gunzipped into bulk. A machine started on it writes to a disk of its own derived from the image, which stays as downloaded.

cd /var/lib/cloonix/bulk
wget https://clownix.net/downloads/kvm_bulk/trixie.qcow2.gz
gunzip trixie.qcow2.gz
cloonix cli nemo add kvm k1 ram=1000 cpu=2 eth=1 trixie.qcow2

The account needs /dev/kvm, /dev/vhost-net and /dev/net/tun: step 1.
