In diesem Fall sollte + die Funktion nur dann ??0?? zurückgeben, wenn das Modul auch wircklich + für den aktuellen Host benötigt wird. Wenn 255 zurückgegeben wird, wird + das Modul nur dann geladen, wenn es von einem andren Modul als + Abhängigkeit deklariert wurde. + +<pre><code class="bash"> +check() { + return 0 +} +</code></pre> + +Als nächstes wird eine ??install??-Funktion erstellt. Die ??install??-Funktion +wird aufgerufen, wenn alle nicht Kernel spezifischen Ressourcen installiert +werden sollen. Es können Binärdateien, Skripte und andere statischen Dateien +installiert werden. Um einen Datei im aktuellen Modul-Ordner zu addressieren +sollte die Variable "$moddir" als Prefix eingesetzt werden. +Eine solche Funktion kann beispielsweise einen ??Command-Line-Hook?? triggern, +der modulespezifische ??Kernel-Command-Line-Optionen?? verarbeitet während das +initiale Minilinux bootet. Im folgenden Beispiel werden ??Command-Line-Optionen +mit Priorität 20 vom Shell-Skript ??parse-insmodpost.sh?? gelesen und +ausgewertet. Dadurch muss natürlich auch das entsprechende Skript in das +initramfs kopiert werden. Dies wird durch den Aufruf der Funktion +??inst_simple?? erreicht. + +<pre><code class="bash"> +install() { + inst_hook cmdline 20 "$moddir/parse-cmdline.sh" + inst_simple "$moddir/parse-cmdline.sh" /sbin/insmodpost.sh +} +</code></pre> + +Die ??parse-cmdline.sh?? parst die Kernel-Command-Line für die Argumente +??rd.driver.post??, verhindert, dass die Module automatisch geladen werden und +installiert den Hook ??hook.sh?? in der ??initqueue/settled??. Der Inhalt von +??parse-cmdline.sh?? könnte wie folgt aussehen: + +<pre><code class="bash"> +for p in $(getargs rd.driver.post=); do + echo "blacklist $p" >> /etc/modprobe.d/initramfsblacklist.conf +done +</code></pre> + +In einer ??depends??-Funktion können andere Dracut-Module als Abhängigkeit +deklariert werden. Diese müssen einfach per "echo" als String Leerzeichen +getrennt ausgegeben werden. + +<pre><code class="bash"> +depends() { + echo 'debug virtfs' +} +</code></pre> + +Mit dieser Funktion können zusätzliche benötigte Kernel-Command-Line-Argumente +ausgegeben werden, die benötigt werden um die aktuelle Maschine zu booten. +Die Ausgabe sollte mit einem Leerzeichen beginnen und keine neuen Zeilen +ausgeben. + +<pre><code class="bash"> +cmdline() { + echo 'TODO' +} +</code></pre> + +Mit der Funktion ??installkernel?? sollen alle kernelspezifischen Dateien +installiert werden. Siehe hierzu auch den Abschnitt +??Hilfsfunktionen zur Installation?? + +<pre><code class="bash"> +installkernel() { + TODO +} +</code></pre> + +h2. Hilfsfunktionen zur Installation + +??inst_multiple?? installiert mehrere Binärdateien. Sollten ausführbare Dateien +ohne entsprechendem Pfad ausgewählt werden, wird dracut folgende die Pfade +??/usr/sbin??, ??/sbin??, ??/usr/bin??, ??/bin?? durchsuchen, um den Pfad der +zugehörigen ausführbaren Datei zu ermitteln. Bei dem Kommando-Zeilen-Argument +??-o?? als erster Parameter werden Fehler bei nicht auffindbaren Dateien +unterdrückt. + +??inst_multiple [-o] <file> [ <file> …]?? + +??inst?? installiert eine referenzierte Datei an den korrespondierenden Ort im +??initramfs??. Die Datei wird innerhalb des ??initramfs?? am gleichen Ort zu +finden sein wie auf der Referenzmaschine. Optional kann als zweites Argument +ein anderer Ort für das temporäre Dateisystem angegeben werden. + +??inst <src> [<dst>]?? + +??inst_hook?? installiert eine ausführbare Datei im Pfad ??<src>?? im +Dracut-hook-Ordner ??<hookdir>??. Der Einstiegspunkt wird mit Priorität +??<prio>?? zur Laufzeit des initialen Mini-Linux-Systems ausgeführt. + +??inst_hook <hookdir> <prio> <src>?? + +??inst_rules?? installiert einen oder mehrere udev-Regeln. Nicht-existente +udev-Regeln werden beim bauen des initramfs gemeldet, führen aber nicht zum +Abbruch. + +??inst_rules <udevrule> [ <udevrule> …]?? + +??instmods?? installiert einen oder mehrere Kernel-Module in das initramfs. +??<kernelmodule>?? kann auch ein komplettes Subsystem darstellen, wenn es mit +dem Prefiy "=" beginnt (z.B. "=drivers/net/team"). ??instmods?? sollte nur +innerhalb der ??installkernel()??-Funktion verwendet werden. Ist ??$hostonly?? +gesetzt und das aktuelle Modul nicht im Referenzsystem geladen und wird +demnach nicht in ??/sys/…/uevent MODALIAS?? verwendet, wird dieses nicht in +das initramfs integriert. Soll das Modul in jedem Fall geladen werden, kann +folgende Syntax verwendet werden: + +<pre><code class="bash"> +installkernel() { + hostonly='' instmods <kernelmodule> +} +</code></pre> + +??instmods <kernelmodule> [ <kernelmodule> … ]?? + +h3.
