Hallo,

nachdem wir uns hier:
http://forums.gentoo.org/viewtopic-t-688483.html
zu einem Stage3 Archiv emporgearbeitet haben, stellt sich natürlich die Frage, wie man ein Stage3 Archiv inklusive Paludis erzeugen könnte...
Nun, nachdem ja catalyst nicht mit paludis zusammenarbeitet, müssen wir das ganze anders angehen:

Das im folgenden erzeugte Stage3 Archiv ist technisch gesprochen nämlich kein Stage3 Archiv, sondern ein Stage4 Archiv.
Das target stage4 von catalyst erlaubt uns nämlich, folgende Variablen zu setzen:
Code:

portage_confdir:
   /root/catalyst/portage
stage4/packages:
   sys-apps/paludis
stage4/fsscript:
   /root/catalyst/fsscript_paludis.sh

Das Vorgehen sollte jetzt schon eindeutiger sein:
Wir weisen catalyst an, paludis zu installieren
Die Datei /root/catalyst/portage/package.keywords muss dementsprechend folgende Einträge enthalten:
Code:

sys-apps/paludis x86 ~x86
app-admin/eselect x86 ~x86
app-admin/eselect-news x86 ~x86

Damit wird dann paludis installiert.
Schlussendlich fehlen eigentlich nur noch zwei Dateien:

/root/catalyst/stage4_paludis.spec
Code:

subarch:
   i686
target:
   stage4
version_stamp:
        XXX_VERSION_STAMP_XXX
rel_type:
   default
profile:
   default/linux/x86/2008.0
snapshot:
   XXX_VERSION_STAMP_XXX
source_subpath:
   default/stage3-i686-XXX_VERSION_STAMP_XXX
portage_confdir:
   /root/catalyst/portage
stage4/packages:
   sys-apps/paludis
stage4/fsscript:
   /root/catalyst/fsscript_paludis.sh
stage4/empty:
   /usr/portage
   /var/paludis/distfiles
   /var/paludis/repositories
   /var/tmp/paludis

und die Datei:
/root/catalyst/fsscript_paludis.sh
Code:

#!/bin/bash
# export HOME for paludis...
export HOME=/root
do_check_status () {
   if [ $? -eq 0 ]; then
      echo ">>> done"
   else
      echo ">>> Error"
      exit 1
   fi
}

if [ -d /etc/paludis ]; then
   echo ">>> /etc/paludis exists, ok..."
else
   echo ">>> creating /etc/paludis..."
   mkdir /etc/paludis
   do_check_status
fi
if [ -d /etc/paludis/keywords.conf.d ]; then
        echo ">>> /etc/paludis/keywords.conf.d exists, ok..."

        echo ">>> creating /etc/paludis/keywords.conf.d..."

        mkdir /etc/paludis/use.conf.d

echo ">>> all done, exiting"
exit 0

Das ganze sollte so ziemlich selbsterklärend sein.
Das Resultat von:
Code:

catalyst -v -f stage4_paludis.spec

ist jedenfalls ein (technisch gesehen Stage4) Stage3 Archiv, das paludis als Paketmanager verwendet.
Das fsscript_paludis.sh beinhaltet die von mir bevorzugte Paludiskonfiguration.
Viele werden diese also an ihre eigenen Bedürfnisse anpassen wollen...
Auch und insbesondere auf die CHOST, CFLAGS, CXXXFLAGS sollte geachtet werden.

Es ist im übrigen klar, dass sich im Laufe der Zeit für paludis benötigte Keywords, Supportpackages,... ändern können (und werden).
Ebenfalls die Konfiguration von Paludis selbst.
Der geneigte Leser und Anwender sollte dann allerdings in der Lage sein, die notwendigen Änderungen selbst durchzuführen...

HTH,
ruth
