|
|
|
|
<para>The command <command>nix-collect-garbage</command> is mostly an
|
|
alias of <link linkend="rsec-nix-store-gc"><command>nix-store
|
|
--gc</command></link>, that is, it deletes all unreachable paths in
|
|
the Nix store to clean up your system. However, it provides an
|
|
additional option <option>-d</option> (<option>--delete-old</option>)
|
|
that deletes all old generations of all profiles in
|
|
<filename>/nix/var/nix/profiles</filename> by invoking
|
|
<literal>nix-env --delete-generations old</literal> on all profiles.
|
|
Of course, this makes rollbacks to previous configurations
|
|
impossible.</para>

<para>To delete from the Nix store everything that is not used by the
|
|
current generations of each profile, do

|
|
|
<screen>
|
|
$ nix-collect-garbage -d</screen>
