-<para>The cause is that two installed packages in the user environment
-have overlapping filenames (e.g.,
-<filename>xml/dtd/docbook/calstblx.dtd</filename>.  This usually
-happens when you accidentally try to install two versions of the same
-package.  For instance, in the example above, the Nix Packages
-collection contains two versions of <literal>docbook-xml</literal>, so
-<command>nix-env -i</command> will try to install both.  The default
-user environment builder has no way to way to resolve such conflicts,
-so it just gives up.</para>
-
-<para>Solution: remove one of the offending packages from the user
-environment (if already installed) using <command>nix-env
--e</command>, or specify exactly which version should be installed
-(e.g., <literal>nix-env -i docbook-xml-4.2</literal>).</para>

-<title><quote>Too many links</quote> Error in the Nix store</title>

-
-<para>Symptom: when building something, you get an error message such as
-
-<screen>
-...
-<literal>mkdir: cannot create directory `/nix/store/<replaceable>name</replaceable>': Too many links</literal></screen>
-
-</para>
-
-<para>This is usually because you have more than 32,000 subdirectories
-in <filename>/nix/store</filename>, as can be seen using <command>ls
--l</command>:
-
-<screen>
-$ ls -ld /nix/store
-drwxrwxrwt 32000 nix nix 4620288 Sep 8 15:08 store</screen>

-The <literal>ext2</literal> file system is limited to an inode link
-count of 32,000 (each subdirectory increasing the count by one).
-Furthermore, the <literal>st_nlink</literal> field of the
-<function>stat</function> system call is a 16-bit value.</para>
-
-<para>This only happens on very large Nix installations (such as build
-machines).</para>
-
-<para>Quick solution: run the garbage collector.  You may want to use
-the <option>--max-links</option> option.</para>
-
-<para>Real solution: put the Nix store on a file system that supports
-more than 32,000 subdirectories per directory, such as ext4.  (This
-doesn’t solve the <literal>st_nlink</literal> limit, but ext4 lies to
-the kernel by reporting a link count of 1 if it exceeds the
-limit.)</para>
