There is a lot of people who run source bootstrap without being aware of the effort it needs to do it properly, so clarify this to make sure everyone knows what's involved.

### Install the bootstrap packages
|
||||
|
||||
The `bootstrap` packages are a set of packages required to build any available source package in a container. There are two methods to install the `bootstrap`:
|
||||
There is a set of packages that makes up the initial build container, called the `bootstrap`.
|
||||
These packages are installed into the `masterdir` in order to create the container.
|
||||
|
||||
- `bootstrap`: all bootstrap packages will be built from scratch; additional utilities are required in the
|
||||
host system to allow building the `base-chroot` package: binutils, gcc, perl, texinfo, etc.
|
||||
The primary and recommended way to set up this container is using the `binary-bootstrap`
|
||||
command. This will use pre-existing binary packages, either from remote `xbps` repositories
|
||||
or from your local repository.
|
||||
|
||||
- `binary-bootstrap`: the bootstrap binary packages are downloaded via XBPS repositories.
|
||||
There is also the `bootstrap` command, which will build all necessary `bootstrap` packages from
|
||||
scratch. This is usually not recommended, since those packages are built using your host system's
|
||||
toolchain and are neither fully featured nor reproducible (your host system may influence the
|
||||
build) and thus should only be used as a stage 0 for bootstrapping new Void systems.
|
||||
|
||||
If you don't want to waste your time building everything from scratch probably it's better to use `binary-bootstrap`.
|
||||
If you still choose to use `bootstrap`, use the resulting stage 0 container to rebuild all
|
||||
`bootstrap` packages again, then use `binary-bootstrap` (stage 1) and rebuild the `bootstrap`
|
||||
packages once more (to gain stage 2, and then use `binary-bootstrap` again). Once you've done
|
||||
that, you will have a `bootstrap` set equivalent to using `binary-bootstrap` in the first place.
|
||||
|
||||
Also keep in mind that a full source `bootstrap` is time consuming and will require having an
|
||||
assortment of utilities installed in your host system, such as `binutils`, `gcc`, `perl`,
|
||||
`texinfo` and others.
