Hi there !<br><br>I&#39;m quitely new to Gentoo, but I&#39;m loving it, so I have projects with it !<br>Some of them may require Catalyst in its process from what I understood about Catalyst.<br><br>I&#39;ll copy/paste a forum post I&#39;ve made before I knew there was a mailing list for Catalyst :<br>

<br><span class="postbody">OK, let me expose things differently since I know a little more what I would like to do and what Gentoo could offer.
<br>

<br>
- I have <span style="font-weight: bold;">a local mirror</span>, which may have overlay packages.
<br>
- I have <span style="font-weight: bold;">a host system</span>, which have Gentoo setup on it.
<br>
- <span style="font-weight: bold;">I want to build barely-usable minimal systems that I call &quot;guests&quot;</span> from my host. Guests would have to be setup on target machines using fdisk and tar only, or put on a Live{CD,DVD,USB}.
<br>

<br>
<span style="text-decoration: underline;">Assuming that I can kinda cross-compile guests binaries from my host system with emerge</span>
(using --root and --portage_configdir, guests have same arch than
host), I would like my host system to entirely build my guest BUT <span style="text-decoration: underline;">I want my guest to be extremely minimal</span>.
My guest don&#39;t have to have sys-devel/* things like binutils, gcc and
so on. It just have to run a few already compiled C++ binaries. <span style="text-decoration: underline;">Everything that my guest need will be emerged from my host</span>.
<br>

<br>
<span style="font-weight: bold;">How can I proceed (the clean way !) from my host to emerge (or copy ?) a fully minimal system to a host dir, like say /guest/</span> ?
<br>
Did I have to &quot;create&quot; a profile on my local mirror which tells that my
&quot;system&quot; meta-port have almost nothing in it ? How can I do this if
it&#39;s the clean way ?<br>Did I have to use Catalyst ? How can I do this if it&#39;s the clean way ?<br><br>Many thanks in advance.<br clear="all"></span><br>-- <br>Pierre.<br>&quot;Sometimes when I&#39;m talking, my words can&#39;t keep up with my thoughts.
