-A new set of 17.1 amd64 profiles has been added to the Gentoo
-repository. Those profiles switch to a more standard 'no SYMLINK_LIB'
-multilib layout, and require explicit migration as described below. They
-are considered experimental at the moment, and have a fair risk
-of breaking your system. We would therefore like to ask our users to
-test them on their non-production ~amd64 systems.
-
-In those profiles, the lib->lib64 compatibility symlink is removed.
-The 'lib' directory becomes a separate directory, that is used
-for cross-arch and native non-library packages (gcc, clang) and 32-bit
-libraries on the multilib profile (for better compatibility with
-prebuilt x86 packages).
-
-Migration from both 13.0 and 17.0 profiles is supported. In case
-of the former, please read the news item for 17.0 upgrade first
-and enable gcc 6.4.0 or newer first as explained there.
-
-The migration is performed using app-portage/unsymlink-lib tool.
-The following steps can be used to upgrade your system:
-
-1. Sync and upgrade your system to the newest package versions
-   to reduce the risk of issues.
-
-2. Install the tool, e.g. via 'emerge -1v app-portage/unsymlink-lib'
-
-3. Run 'unsymlink-lib --analyze' and check the output for obvious
-   mistakes. If you need to perform any changes to the system, remember
-   to run 'unsymlink-lib --analyze' again afterwards.
-
-[past this point do not call emerge or modify /usr manually]
-
-4. This is a very good time to make a backup.
-
-5. Run 'unsymlink-lib --migrate'. You can add '--pretend' first to see
-   what is going to happen.
-
-6. Reboot your system and see if it still boots. Check if important
-   programs work. In particular, check if e.g. 'emerge --info' works
-   (but do not install anything). If you hit any serious problems,
-   you can use 'unsymlink-lib --rollback' to revert the changes
-   and return to step 3.
-
-7. Run 'unsymlink-lib --finish'. You can add '--pretend' first to see
-   what is going to happen but note that you're going to see a very long
-   list of files to remove.
-
-8. Switch the profile, e.g.:
-
-     eselect profile set --force default/linux/amd64/17.1/desktop
-
-[at this point you can start using emerge again]
-
-9. Rebuild sys-devel/gcc. If you are switching from 13.0 profiles,
-   rebuild sys-devel/binutils and sys-libs/glibc afterwards.
-
-10. If you are using a multilib profile, rebuild all 32-bit packages.
-    This can be done using:
-
-      emerge -1v /lib32 /usr/lib32
-
-    Alternatively, if you are switching from one of the 13.0 profiles
-    you can rebuild all packages as detailed in the 17.0 news item.
-
-11. Once the last 32-bit package is rebuilt, your package manager
-    should remove the orphaned /lib32 and /usr/lib32 symlinks. If that
-    does not happen, remove them manually.
-
-For known issues, please see bug #506276 [1]. If you have any problems
-with the new profiles or the migration procedure, please report a bug
-and make it block the tracker.
-
-For more information on the layout, please see the wiki article
-on AMD64 multilib layouts [2].

+A new set of 17.1 amd64 profiles has been added to the Gentoo
+repository in Dec 2017.  These profiles switch to a more standard
+'no SYMLINK_LIB' multilib layout, and require explicit migration as
+described below.  They are considered stable at the moment, and we would
+like to request all users to upgrade their systems.  The old profiles
+will be deprecated in the near future.
+
+In the new profiles, the lib->lib64 compatibility symlink is removed.
+64-bit libraries need to be installed directly to lib64.  /lib
+and /usr/lib become real directories, that are used for cross-arch
+and native non-library packages (gcc, clang) and 32-bit libraries
+on the multilib profile (which improves compatibility with prebuilt x86
+packages).
+
+Migration from both 13.0 and 17.0 profiles is supported.  In case
+of the former, reading the news item for 17.0 upgrade [1]
+is recommended.
+
+The migration is performed using app-portage/unsymlink-lib tool.
+The following steps can be used to upgrade your system:
+
+1. Sync and upgrade your system to the newest package versions
+   to reduce the risk of issues.
+
+2. If you are still running a 13.0 profile, select gcc 6.4.0 or later
+   as the system compiler, source /etc/profile and reinstall libtool:
+
+     # gcc-config -l
+     [1] x86_64-pc-linux-gnu-5.5.0 *
+     [2] x86_64-pc-linux-gnu-8.3.0
+     # gcc-config 2
+     # . /etc/profile
+     # emerge -1v libtool
+
+3. Install the tool:
+
+     # emerge -1v app-portage/unsymlink-lib
+
+4. Run 'unsymlink-lib --analyze' and check the output for obvious
+   mistakes.  If you need to perform any changes to the system, remember
+   to run 'unsymlink-lib --analyze' again afterwards.
+
+[past this point do not call emerge or modify /usr manually]
+
+5. This is a very good time to make a backup.
+
+6. Run 'unsymlink-lib --migrate'.  You can add '--pretend' first to see
+   what is going to happen.
+
+7. Reboot your system.  Check if important programs work.
+   In particular, verify that e.g. 'emerge --info' works (but do not
+   install anything).  If you hit any serious problems, you can use
+   'unsymlink-lib --rollback' to revert the changes and return to
+   step 4.
+
+8. Run 'unsymlink-lib --finish'.  You can add '--pretend' first to see
+   what is going to happen but note that you're going to see a very long
+   list of files to remove.
+
+9. Switch the profile, e.g.:
+
+     # eselect profile set default/linux/amd64/17.1/desktop
+
+[at this point you can start using emerge again]
+
+10. Rebuild the toolchain:
+
+      # emerge -1v sys-devel/gcc:8.3.0
+      [ repeat for other slots you will be using ]
+      [ if you are upgrading from 13.0 profile, also: ]
+      # emerge -1v sys-devel/binutils
+      # emerge -1v sys-libs/glibc
+
+11. If you are using a multilib profile, rebuild all 32-bit packages.
+    This can be done using:
+
+      # emerge -1v /lib32 /usr/lib32
+
+    Alternatively, if you are switching from one of the 13.0 profiles
+    you can rebuild all packages as detailed in the 17.0 news item:
+
+      # emerge -ev @world
+
+12. Once the last 32-bit package is rebuilt, your package manager
+    should remove the orphaned /lib32 and /usr/lib32 symlinks.  If that
+    does not happen, remove them manually:
+
+      # rm /lib32 /usr/lib32
+
+For known issues, please see bug #506276 [2].  If you have any problems
+with the new profiles or the migration procedure, please report a bug
+and make it block the tracker.
