Upgrade Instructions/1.4-release

Introduction

The goal of these instructions is to provide Funtoo Linux users with a reliable, consistent set of instructions for upgrading Funtoo Linux from 1.3 to 1.4.

Note that while Portage has some ability to upgrade packages, it is not perfect at performing complex updates right now. One of the primary motivations to have official Funtoo releases is for the purpose of identifying these upgrade challenges and implement improvements to Portage and associated tools to make the process better. Before Portage can be made better, we need to start documenting the various commands required to perform these updates, and that is where these instructions come in.

Overview

With the intended purpose of these instructions in mind, it is recommended to perform a fresh install of Funtoo Linux 1.4 if possible. This is not practical or feasible, follow the steps in this documentation to upgrade Funtoo Linux. The process is straightforward.

Please assist in ensuring that these instructions are complete, make changes to the page that are needed to make these instructions 100% reliable, and if the instructions seem to not work properly, please consider opening a bug at https://bugs.funtoo.org or asking for assistance at https://forums.funtoo.org or #funtoo on freenode. Do not make major changes to this document without first opening a bug related to the issue so your changes can be reviewed. Thank you!

Set Release and Sync

Use your favorite editor in /etc/ego.conf, set the release to 1.4:

/etc/ego.conf

[global]

release = 1.4

Then, run ego sync:

root # ego sync

If you are seeing an error like

ERROR: Malformed update entry 'move >=dev-lang/lua-5.3 dev-lua/lua'

at the bottom of the ego sync output, that can be ignored. It is an expected error and caused by a new portage command that can't be handled by the installed portage version but will be resolved by the new version that is installed during the upgrade process.

Set gfxcard mix-ins and VIDEO_CARDS

In Funtoo Linux 1.4, the VIDEO_CARDS make.conf setting has been updated and mix-ins have been created to allow you to easily choose common configurations. It is strongly recommended that you select your video hardware using Funtoo mix-ins, not VIDEO_CARDS directly, by choosing a mix-in from the following list:

Funtoo Graphics Mix-Ins

gfxcard-intel: This mix-in is equivalent to gfxcard-intel-classic or gfxcard-intel-iris, depending on the release you're running. Currently, it defaults to gfxcard-intel-classic on 1.4-release and to gfxcard-intel-classic on Next release. Do not enable more than 1 gfxcard-intel* mix-in at the same time. The result is not what you might expect.
gfxcard-intel-classic: This mix-in enables Intel graphics support based on the older i915 mesa driver (not to be confused with the i915 kernel driver). Choose this if you have a Gen3 or older chipset.
gfxcard-intel-iris: This mix-in enables Intel graphics support for cards with glamor modesetting support (drivers i965 or iris), including support OpenGL ES (>=Gen4) and OpenCL and Vulkan (>=Gen7) and video acceleration where available. If your card is >=Gen5, do an emerge libva-intel-driver or emerge media-libs/libva-intel-media-driver (for >=Gen8) afterwards to ensure you have full video acceleration support.
gfxcard-amdgpu: This mix-in enables support for modern Radeon cards, Southern Islands -- GFX Core 6 (see this x.org reference) and greater. Includes Vulkan and video acceleration where available. Drivers are built for both the Gallium framework (modern replacement for DRI framework) and DRI framework. Glamor is used to accelerate 2D operations.
gfxcard-radeon: This mix-in enables support for modern Radeon cards, R600 through Northern Islands -- GFX Core 4 and 5 (see this x.org reference). Drivers are built for the Gallium framework (modern replacement for DRI framework) as well as DRI framework. Glamor is used to accelerate 2D operations.
gfxcard-older-ati: Use this mix-in to enable support for R300 up to (but not including) R600 Radeon cards -- -- GFX Core 3 (see this x.org reference). DRI as well as Gallium-based drivers are enabled.
gfxcard-ancient-ati: Use this mix-in to enable support pre-R300 cards -- GFX Core 1 and 2 (see this x.org reference). These drivers are DRI-based.
gfxcard-nvidia: Use this to enable support for proprietary NVIDIA drivers. You will also need to emerge nvidia-kernel-modules, blacklist nouveau and add yourself to the video group. See this documentation for more details. Note that Funtoo now has two catpkgs for NVIDIA proprietary graphics -- nvidia-drivers and nvidia-kernel-modules -- to aid the use of NVIDIA acceleration on containers.
gfxcard-nvidia-legacy: Proprietary NVIDIA drivers like above, but the legacy version of the driver that supports older hardware. See https://www.nvidia.com/en-us/drivers/unix/ and browse the specific driver version that emerge is installing to get detailed compatibility information.
gfxcard-nouveau: Use this mix-in to enable support for Open Source nouveau drivers.

Another important change for NVIDIA proprietary graphics users -- a new package nvidia-kernel-modules is now used to install the NVIDIA kernel modules. nvidia-drivers will only install the userland components. To emerge both, emerge nvidia-kernel-modules which will in turn pull in nvidia-drivers. This is set up this way because it is possible to set up an NVIDIA-accelerated container (see LXD/GPU Acceleration) that needs nvidia-drivers but not kernel modules.

Here is an example of how to add a mix-in to your profile:

root # epro mix-ins +gfxcard-nvidia

=== Enabled Profiles: === 

        arch: x86-64bit
       build: current
     subarch: intel64-westmere
      flavor: desktop
     mix-ins: mediaformat-gfx-common
     mix-ins: gfxcard-nvidia

>>> Set mix-in gfxcard-nvidia.

Upgrade Toolchain

Funtoo 1.4, gcc has been updated to 9.2.0 series by default, so lets take advantage of that, and also update binutils and glibc. Note that multiple versions of gcc, 9.2.0 and 7.4.1, may get pulled in in while upgrading gcc. Only 9.2.0 is needed in Funtoo 1.4, so once 9.2.0 is installed, you may cancel the emerge of older versions of gcc to save time.

root # emerge -u1 gcc
root # emerge -u1 binutils
root # binutils-config -l
root # binutils-config 3 (or whatever number corresponds to version 2.32)
root # source /etc/profile
root # emerge -u1 glibc

World Update

Before starting the world update, it is a good idea to upgrade python. Do so as follows:

root # emerge -u =dev-lang/python-3.7*

Once this is done, we will temporarily want to tell emerge to build python modules for versions 2.7, 3.6 and 3.7. We are doing this so that dependencies resolve correctly for installed packages still using python-3.6, and will "undo" this setting and rebuild these packages later:

root # export PYTHON_TARGETS="python3_7 python3_6 python2_7"

At this point, you should be all set to perform a world update. We will exclude perl from upgrading now as we will do that near the end of the install.

root # emerge -auDN @world --jobs=3 --exclude dev-lang/perl

It seems that excluding perl can cause some issues with the dep graph currently. If that is the case you can try the complete world update.

root # emerge -auDN @world --jobs=3

Perl Upgrade

If you have not excluded perl from the world update, you probably already have the current perl version installed. But you can verify that with

root # emerge -pv dev-lang/perl

If there is no update available you are good. Otherwise you need to install it with

root # emerge dev-lang/perl

followed by

root # perl-cleaner --all

to make sure that there are no outdated perl packages left.

If you have excluded perl from the world update you would have a complete but old perl installation. Now that things are upgraded, we can take care of perl, and rebuild all perl modules and perl-dependent things against the new perl:

root # emerge -u1 dev-lang/perl 
root # perl-cleaner --all

Finishing Steps

Remove python-3.6 as it will no longer be used, and rebuild anything that has python-3.6 modules installed:

root # unset PYTHON_TARGETS
root # emerge -C =dev-lang/python-3.6*
root # emerge -auDN @world
root # eselect python cleanup

If you are using debian-sources-lts, it has now been updated to 4.19.37_p6. Edit /etc/boot.conf as necessary and run ego boot update to ensure the new kernel is booted upon next system startup.

root # ego boot update

etc-update and Reboot

Before rebooting, it is a good idea to run etc-update to apply updates to any configuration files that require updating:

root # etc-update

Now, you should be able to reboot into Funtoo Linux 1.4:

root # reboot

Enjoy!
