USB Festplatte wird beim Start (10.1) nicht gemounted -udev-hal - Vorschlag - mountpoint prüfen ?

28 Jun 2006

      Hallo
im thread 
USB Festplatte wird beim Start (10.1) nicht gemounted
Von: David Geiger 
An: suse-linux@suse.com,  Fri May 26 12:21:11 2006
wurde schon gesagt, dass es ein Problem ist, wenn eine USB-Platte vor dem 
booten an war. Denn dann sieht man es später nicht - ohne manuelles mounten.
Nun habe ich mir das näher angesehen. Ich hoffe der Anhang erklärt, was ich 
gemacht habe 

Für mich ist jetzt nur noch eine Frage:
In 
./usr/lib64/hal/scripts/hal-system-storage-mount
wird der Mountpoint auf erlaubte Zeichen geprüft:
               GIVEN_MOUNTPOINT=${GIVEN_MOUNTPOINT//[^a-zA-Z0-9_+-]/_}
Damit ist es nicht möglich ein Verzeichnis anzugeben. Was wohl gewünscht ist.
Was ich aber nicht mag.

Wie muesste man diese zeile ändern, sodass '/' erlaubt ist, aber nicht als 
erstes Zeichen?
Ist ein Mount-point, der ein Verzeichniss ist wirklich schlecht oder 
gefährlich?

Zum Beispiel wird aus dem gewünschten MP.
wd1200/daten
wd1200_daten

Mit meiner Aenderung wird aus
/wd1200/daten
/wd1200/daten
Doch da hätte ich gerne
_wd1200/daten
d.h. einen absoluten Pfad würde ich schon vermeiden wollen.

Ansonsten verstehe ich die hal-specifikation so, das man den Knoten zum 
einbinden der Laufwerke anpassen kann. 
Doch ./usr/lib64/hal/scripts/hal-system-storage-mount überschreibt das 
mit /media.

Ich hoffe ich konnte euch ein bisschen helfen und Ihr
habt Ideen wie man den MP prüft.

Gruss Hugo
