Nein. Version aus Sid nehmen, oder einige Tage warten, bis gefixtes
cdrecord in Woody ist.

Skript im Anhang. Alternativ, mutt-Macros.

Q/A von mir:
6a)
Q: Wie baue ich eigene Sachen in ein Init-Skript ein, und in welches?
A:
cd /etc/init.d
cp skeleton mein_skript
(entweder alles ordentlich anpassen, oder, für Kleinigkeiten, alles bis
auf die erste Zeile löschen und hinterher schreiben)
update-rc.d mein_skript defaults
- Details in "man update-rc.d".
- Wieder entfernen mit "update-rc.d mein_skript remove"

Locales konfigurieren, channel.debian.de/faq

Da gab es einige Tips vor wenigen Tagen. Für einfache Backups:
tar zcv --one-file-system -p -s --same-owner --numeric-owner --sparse -f backupfile.tgz /pfad
Das macht man mit jedem Dateisystem oder Verzeichniss. Andere
Dateisysteme werden nicht mitgesichert (z.B. /proc oder reingemountete
Dateisysteme). --exclude=xyz kann best. Pfade/Dateien ausschliessen.

cp /dev/hda /dev/hde

man init

man runlevel.conf
(mir gefällt file-rc auch)
Gruss/Regards,
