Gentoo
========
Use a Gentoo cloud image as the baseline for built disk images. The images are
located in profile specific sub directories:
http://distfiles.gentoo.org/releases/amd64/autobuilds/
As of this writing, only x86_64 images are available.
Notes:
* There are very frequently new automated builds that include changes that
happen during the product maintenance. The download directories contain an
unversioned name and a versioned name. The unversioned name will always
point to the latest image, but will frequently change its content. The
versioned one will never change content, but will frequently be deleted and
replaced by a newer build with a higher version-release number.
* In order to run the package-installs element you will need to make sure
`dev-python/pyyaml` is installed on the host.
* In order to run the vm element you will need to make sure `sys-block/parted`
is installed on the host.
* Other profiles can be used by exporting GENTOO_PROFILE with a valid profile.
A list of valid profiles follows:
default/linux/amd64/13.0
default/linux/amd64/13.0/no-multilib
hardened/linux/amd64
hardened/linux/amd64/no-multilib
* You can set the GENTOO_PORTAGE_CLEANUP environment variable to true (or
anything other than False) to clean up portage from the system and get the
image size smaller.
* Gentoo supports many diferent versions of python, in order to select one
you may use the `GENTOO_PYTHON_TARGETS` environment variable to select
the versions of python you want on your image. The format of this variable
is a string as follows `"python2_7 python3_5"`.
* In addition you can select the primary python version you wish to use (that
which will be called by running the `python` command. The
`GENTOO_PYTHON_ACTIVE_VERSION` is used to set that mapping. The variable
contents can be something like `python3.5`.
