<h3>[Step 1/5] Packages and Kernel</h3>

<p>The file <tt>/etc/packages.conf</tt> in the initramfs holds all information
to rebuild your Tiny SliTaz system. You should upload your
<tt>/etc/packages.conf</tt> first if you only want to upgrade your system.</p>

<p>You can upload a tazpkg file (.tazpkg) or a tarball of tazpkg files (.tar).
These packages will extend the official packages list and will be chosen when
the package names are found to be matching. You can find some examples in the
<a href="http://hg.slitaz.org/wok-tiny/file/">Tiny SliTaz repository</a>.</p>
