Update Gentoo element for element changes
There have been a few changes over the past few months, here we make the following changes. * change from backtrack=99 to complete-graph as a more correct flag * make python version selection more in line with what gentoo supports * set up python before stuff gets pip installed * ensure we have the proper pip so we can install pip packages as root * ensure we have the proper use flags for the disk formatting changes * set DIB_RELEASE like other distros * fix openssh-server element for gentoo Change-Id: I17202de3016616ce34c8cbead7d0fb047a64e96b

|
||||
* 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`.
