[gentoo-alt] [PREFIX] disabling Python-2 by default?

[gentoo-alt] [PREFIX] disabling Python-2 by default?

Hi,

Now we're using python-3 to bootstrap in stage1 (this has still some
issues on some platforms, but I'm assuming we can fix those), I've been
wondering myself whether we should disable python-2 by default in
Prefix.  It would reduce some compilation time and files/disk footprint.

Opinions, thoughts, ideas on disabling python-2 by default?

(Obviously, people can enable and install python-2 after bootstrap,
there's no plans to remove the ebuild from the tree at this time.)

Thanks,
Fabian

I agree with you.  We only need bootstrap to produce a minimal system
for people to start with.  If anything could be gotten rid of to make
bootstrap simpler, it should happen.

Yours,

[gentoo-alt] [PREFIX] Python-2 now disabled by default

Python-2 is now disabled by default via
https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=e9de14ba

Since this changes the default for *all* users:
- if you want to keep python2_7, in your etc/portage/make.conf:
  PYTHON_TARGETS="python2_7 python3_6"
- if you're ok without python2_7, rebuild things to avoid dependency
  problems:
  emerge -Duva --newuse world

Above after you synced to a tree that contains the change (in an hour
from now or so).

Thanks,
Fabian
