<title>Garbage Collector Roots</title>
|
|
|
|
<para>The roots of the garbage collector are all store paths to which
|
|
there are symlinks in the directory
|
|
<filename><replaceable>prefix</replaceable>/nix/var/nix/gcroots</filename>.
|
|
For instance, the following command makes the path
|
|
<filename>/nix/store/d718ef...-foo</filename> a root of the collector:
|
|
|
|
<screen>
|
|
$ ln -s /nix/store/d718ef...-foo /nix/var/nix/gcroots/bar</screen>
|
|
|
|
That is, after this command, the garbage collector will not remove
|
|
<filename>/nix/store/d718ef...-foo</filename> or any of its
|
|
dependencies.</para>
|
|
|
|
<para>Subdirectories of
|
|
<filename><replaceable>prefix</replaceable>/nix/var/nix/gcroots</filename>
|
|
are also searched for symlinks. Symlinks to non-store paths are
|
|
followed and searched for roots, but symlinks to non-store paths
|
|
<emphasis>inside</emphasis> the paths reached in that way are not
|
|
followed to prevent infinite recursion.</para>
