moss and boulder

A rewrite of the Serpent OS tooling in Rust, enabling a robust implementation befitting Serpent and Solus

The Rust re-implementations of moss and boulder have now exceeded the capabilities of the original PoC code bases.

It is recommended to use an up to date version of Rust via rustup.

Status

Current Milestone target: oxide-prealpha1

• Read support for .stone
• Repository manipulation
• Plugin system for layered graph of dependencies
• Search support
• Transactions
• Installation support
• Removal support
• sync support (See: #73 (comment))
• Triggers
• GC / cleanups of latent states
• boulder ported
• Features (previously: Subscriptions)

Onboarding

# clone the serpent-os moss repo somewhere reasonable
mkdir -pv ~/repos/serpent-os/
cd ~/repos/serpent-os/
git clone https://github.com/serpent-os/tools.git
cd tools/

# from inside the moss clone, this will build boulder and moss
# and install them to ${HOME}/.local/bin/ by default
just get-started

# boulder and moss rely on so-called subuid and subgid support.
# IFF you do not already have this set up for your ${USER} in /etc/subuid and /etc/subuid
# you might want to do something similar to this:
sudo touch /etc/sub{uid,gid}
sudo usermod --add-subuids 1000000-1065535 --add-subgids 1000000-1065535 root
sudo usermod --add-subuids 1065536-1131071 --add-subgids 1065536-1131071 ${USER}

NB: If you want to build .stones with boulder on your non-serpent host system, you will need to specify the location of the boulder data files (which live in ${HOME}/.local/share/boulder if you used just get-started like above):

alias boulder="${HOME}/.local/bin/boulder --data-dir=${HOME}/.local/share/boulder/ --config-dir=${HOME}/.config/boulder/ --moss-root=${HOME}/.cache/boulder/"

Documentation

See docs.serpentos.com.

Experiment

NB: Remember to use the -D sosroot/ argument to specify a root directory, otherwise moss will happily eat your current operating system.

just get-started

# create the sosroot/ directory
mkdir -pv sosroot/

# Add the volatile repo
moss -D sosroot/ repo add volatile https://dev.serpentos.com/volatile/x86_64/stone.index

# List packages
moss -D sosroot/ list available

# Install something
moss -D sosroot/ install systemd bash libx11-32bit

If you want to create systemd-nspawn roots or bootable VMs, please check out the img-tests repository.
