The `build.packages` and `install.packages` files in the CONFIGDIR now
only need to include *additional* packages to install. The packages
*required* for Aimee OS are always installed, listed in the
corresponding files in the source directory.
In effort to support different builds of Aimee OS using the same
scripts, without necessarily having to fork this repository, the build
system now supports a `CONFIGDIR` setting. When this variable is set,
files defining the target environment, such as the lists of packages to
install, the kernel configuration, the Portage configuration, etc. are
found in the path it specifes.
The reference build, for the Home Assistant Yellow board, is configured
in the `yellow` directory. To build it, run:
```sh
CONFIGDIR=yellow ./vm-build.sh
```
The *aimee-os* SELinux policy module provides rules that are specific to
our custom commands and system configuration. These rules are not
suitable for including in the upstream policy, so we include them in a
separate package rather than patches to the base policy.
Currently, the policy module includes rules to allow the `init-storage`
and `system-update` programs to work. It also includes rules to allow
SSH host keys to be stored in `/var/lib/ssh` instead of `/etc/ssh`,
since our `/etc` is immutable.
The Portage packages that need to be built and/or installed are now
specified in the `build.packages` and `install.packages` files,
respectively. Similarly, packages to be installed on the host system
are specified in `host-tools.packages`. Finally, the
`installonly.packages` file contains a list of packages that are
installed in the destination root, but not built in the sysroot
beforehand.
This allows `make` to better track when the package sets change. It
will also make it easier to maintain different sets for different
variants in the future.
