+The amd64 17.1 profiles switch to a more standard 'no SYMLINK_LIB' 
+multilib layout, and require an explicit migration.
+The migration is performed using the 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:
+     # 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.  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 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 default/linux/amd64/17.1/desktop
+
+[at this point you can start using emerge again. emerge will then 
+ not display this message anymore, but the remaining steps are still 
+ required!]
+
+9. Rebuild gcc:
+      # emerge -1v sys-devel/gcc:9.3.0
+      [ repeat for other slots you will be using ]
+
+10. If you are using a multilib profile, rebuild all 32-bit packages.
+    This can be done using:
+      # emerge -1v --deep /lib32 /usr/lib32 /usr/lib/llvm/*/lib32
+
+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:
+      # rm /lib32 /usr/lib32
+
+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.
