升级说明/1.3-release

   Warning

Upgrading to 1.3 will remove any 32-bit compatibility on your system, as we have deprecated multilib support! Please be aware of this before starting the upgrade process.

   Important

The goal of these instructions is to provide Funtoo Linux users with a reliable, consistent set of instructions for upgrading Funtoo Linux from 1.2 to 1.3. Please assist in ensuring that these instructions are complete and guide users through any potential complications. Since this is a wiki, make changes to the page that are needed to make these instructions 100% reliable. Thank you!

Prior to 1.3

Prior to upgrading to 1.3, you will need to perform an ego sync under 1.2. If you encounter errors with ego sync not completing successfully on xorg-kit or gnome-kit, perform the following steps to correct your tree. First, add the following to /etc/ego.conf:

   /etc/ego.conf

[global]

kits_depth = 20

然后，运行以下命令：

root # rm -rf /var/git/meta-repo
root # ego sync

Now, make sure you have ego 2.7.2 or later installed, as this will be required to start the upgrade process.

Set Release and Sync

In /etc/ego.conf, set the release to 1.3:

   /etc/ego.conf

[global]

release = 1.3

Then, run ego sync:

root # ego sync

Optionally Retarget Pure64

If you are running a pure64 build of Funtoo Linux, you will need to run the following command to update your /etc/portage/make.profile/parent file to no longer reference the pure64 arch profile, as it has been deprecated. Run the following command:

root # epro arch x86-64bit
root ##y##WARNING: Previous value: x86-64bit -- typically, user should not change this.

=== Enabled Profiles: ===

        arch: x86-64bit
       build: current
     subarch: intel64-westmere
      flavor: core
     mix-ins: mediaformat-gfx-common
     mix-ins: mediaformat-gfx-extra

>>> Set arch to x86-64bit.
Updating profiles at /etc/portage/make.profile/parent...

   Note

You may also need to update subarch using a similar set of arguments to epro, e.g. from intel64-westmere-pure64 to intel64-westmere.

Optionally Remove Xorg-Server

1.3-release contains a completely reworked xorg-server, and as such, it is best to remove your old xorg-server prior to updating:

root # emerge -C xorg-server
root # emerge -aC $(qlist -IC x11-proto)
root # emerge --oneshot x11-base/xorg-proto

Relax Deps and Rebuild

Before upgrading, it is a good idea to perform the following commands to relax any existing 32-bit ABI deps so that installed packages don't block necessary updates. Be sure to back up /var/db/pkg, as included in the instructions below, and specify the find commands below exactly -- best to copy and paste:

root # cd /var/db
root # cp -a pkg /var/tmp/pkg.bak
root # cd pkg
root # find -iname RDEPEND -exec sed -i -e 's/\[abi_x86_32(-),abi_x86_64(-)]//g' {} \;
root # find -iname RDEPEND -exec sed -i -e 's/,abi_x86_32(-),abi_x86_64(-)]/]/g' {} \;

Any critical installed packages should no longer depend on ebuilds providing 32-bit ABIs.

Now, proceed to install the new gcc, remove the old one, and then upgrade glibc:

root # emerge -u1 gcc
root # emerge -C =sys-devel/gcc-7.3.1*
root # emerge -u1 glibc

Perl Rebuild

With 1.3-release dev-lang/perl updated from 5.24 to 5.26 version. It is necessary to rebuild perl modules installed with such major version update, which can be done with:

root # emerge -v1 --nodeps dev-lang/perl
root # perl-cleaner --all

   Note

Some systems may require perl-cleaner --reallyall

Now, you are ready to proceed with a full system and world update:

root # emerge -auDN @system --ignore-world
root # emerge -auDN @world

Now, it should be possible to rebuild any necessary packages to get rid of preserved libraries, paying particular attention to any old versions of glibc:

root # emerge -av @preserved-rebuild

   Important

It appears that dev-lang/go will keep rebuilding against a preserved 32-bit glibc, so to fully remove multilib on a system that has dev-lang/go installed, you will need to perform the following steps: emerge -C dev-lang/go; emerge dev-lang/go.

Now, after update and rebuild you will want to either run etc-update or dispatch-conf to perform changes to the configuration files that may happen with ebuild updates:

root # etc-update

Optionally Update Kernel

If you were not using debian-sources-lts before, you may want to upgrade to this kernel. Do this as follows:

root # emerge -av debian-sources-lts
root # ego boot update

Depending on your /etc/boot.conf settings, you may need to tweak the file in order to have debian-sources-lts selected by default.

   Important

Remember to rebuild any necessary kernel modules!

This can be achieved with:

root # emerge -av @module-rebuild --exclude debian-sources-lts

Reboot

At this point, we recommend rebooting the system to ensure you are running in the new environment:

root # reboot
