<para>This chapter is for impatient people who don't like reading
|
|
documentation. For more in-depth information you are kindly referred
|
|
to the following chapters.</para>

<listitem><para>Download a source tarball or RPM from <link
|
|
xlink:href='http://www.cs.uu.nl/groups/ST/Trace/Nix'/>. Build source
|
|
distributions using the regular sequence:

$ tar xvfj nix-<replaceable>version</replaceable>.tar.bz2
|

$ ./configure
|
|
$ make
|

$ make install <lineannotation>(as root)</lineannotation></screen>
|
|
|
|
This will install Nix in <filename>/nix</filename>. You shouldn't
|
|
change the prefix if at all possible since that will make it
|
|
impossible to use our pre-built components. Alternatively, you could
|
|
grab an RPM if you're on an RPM-based system. You should also add
|
|
<filename>/nix/etc/profile.d/nix.sh</filename> to your
|
|
<filename>~/.bashrc</filename> (or some other login
|
|
file).</para></listitem>

$ nix-channel --update</screen>
|

|
|
Note that this in itself doesn't download any components, it just
|
|
downloads the Nix expressions that build them and stores them
|
|
somewhere (under <filename>~/.nix-defexpr</filename>, in case you're
|
|
curious). Also, it registers the fact that pre-built binaries are
|
|
available remotely.</para></listitem>

<screen>
|
|
$ nix-env -i hello firefox <replaceable>...</replaceable> </screen>
|
|
|

This should download the pre-built components; it should not build
|
|
them locally (if it does, something went wrong).</para></listitem>

<listitem><para>To keep up-to-date with the channel, do:
|
|
|
|
<screen>
|
|
$ nix-channel --update
|
|
$ nix-env -u '*'</screen>
|
|
|
|
The latter command will upgrade each installed component for which
|
|
there is a “newer” version (as determined by comparing the version
|
|
numbers).</para></listitem>

<listitem><para>If you're unhappy with the result of a
|
|
<command>nix-env</command> action (e.g., an upgraded component turned
|
|
out not to work properly), you can go back:
|
|
|
|
<screen>
|
|
$ nix-env --rollback</screen>
|
|
|
|
</para></listitem>
|
|
|
|
<listitem><para>You should periodically run the Nix garbage collector
|
|
to get rid of unused packages, since uninstalls or upgrades don't
|
|
actually delete them:
|
|
|
|
<screen>
|
|
$ nix-env --delete-generations old
|
|
$ nix-store --gc</screen>
|
|
|
|
The first command deletes old “generations” of your profile (making
|
|
rollbacks impossible, but also making the components in those old
|
|
generations available for garbage collection), while the second
|
|
command actually deletes them.</para></listitem>
