Overview
- Base chroot environment for the creation of most binary packages which will be copied to the Binary Package Server.
- Packages, which don't need to be built, for example Oracle's Java SE Development Kit (JDK), can be fetched from the Mirror Server.
- Software stacks built upon specialized binary packages, require their own chroot environment. If possible, avoid this.
- For reproducibility, Portage and Profiles are frozen with the help of version control system (git in our case). This is only done on the Mirror Server.
- When building packages in a chroot environment, the portage and overlay versions need to set.
Chroot Setup
Preparation
At least the following is required beforehand to ensure reproducible building:
- a versioned portage tree
- versioned overlays (if any)
Setup
- Create a staging root and extract a stage3 or stage4 tarball
- Mount proc, sys and dev (required for portage to control the tty, determine available storage space, etc.)
- Copy /etc/resolv.conf
- Enter the chroot
Note
We are deliberately using a special command to enter the chroot to avoid leaking environment variables
