+===== Troubleshooting =====
+  * If you can't get to the login then press ctrl+c right after /dev and sda3 is mounted.
+  * If your root file system is read-only then use ''mount -t ext3 -o rw,remount /dev/sda3 /'' to get write access.
+  * Current e2fsprogs 1.40.4 fails to build with following error: ''../../lib/libuuid.so: undefined reference to `___tls_get_addr' '' See http://bugs.gentoo.org/show_bug.cgi?id=204102 for more details. Workaround is to use version 1.40.3 by running ''echo '>=sys-fs/e2fsprogs-1.40.4' >> /etc/portage/package.mask'' before emerging.
+==== Installing an older package ====
+Current version gentoo packages may not work on DSM-G600.
+If you gets Masked packages because of unsupported EAPI or package only support kernel 2.6,
+try to install an older package by browsing to /usr/portage///category/application// or going to the CSV tree :
+[[http://sources.gentoo.org/viewcvs.py/gentoo-x86/]]
+and searching older version of the package.
+Once the version found, install it with this command :
+<code>
+emerge -av =category/package-version
+</code>
