# Build Isolation

Each orchestrator run uses `workdir/<architecture>/build-<identifier>/`.
The rootfs, bootloaders, ISO staging tree, and `build_host` belong to that run.
Cleanup and unmounting are limited to the assigned directory.

`--no-clean` preserves the directory for inspection; it does not reuse the
rootfs in a new run. Two builds cannot write to the same output path at once.
Use different output names to keep both images.

Automatic tarballs are separated by configuration in `cache/tarballs/`.
Legacy generic tarballs are no longer selected automatically.
A tarball explicitly selected with `--use-tarball /path` remains a user choice;
its contents are included in the new build.

The XBPS cache and `custom_packages` continue to store reusable packages; they
are not rootfs or staging directories. Calamares builds continue to use their
dedicated environment in `workdir/void-packages`.
