Hey Nils :)

Gute Sache, die FAQ.

A03: Since Knoppix 3.1 2002-12-12, the included knx-hdinstall 0.35
allows installing to ext2, ext3 and reiserfs filesystem types.

Anmerkung:
Die Versionsnummer ist tatsaechlich 0.35, nicht 0.351. Das liegt
daran, dass Klaus als Grundlage fuer seine letzten Aenderungen an
knx-install diese Version als Grundlage verwendet hat, waehrend ich
die Version 0.351 mit einem aehnlichen Bugfix released habe.

Wenn ich es zeitlich schaffe, release ich vor Weihnachten noch eine
Version mit xfs-Support, franzoesischen Meldungen und weiteren
Kleinigkeiten.

Absolute Zustimmung. Die noetigen Sanity-Checks wuerden das Skript
schaetzungsweise um 50% aufblaehen.

Wenn das knoppix.sh-Skript im Verzeichnis /KNOPPIX auf der CD (nicht
im cloop-Mountpoint) liegt, wird es unabhaengig vom Bootparameter
"floppyconfig" ausgefuehrt.

Fuer diesen Fall habe ich vor einiger Zeit ein kleines Shellskript
"changeconf" geschrieben:

#!/bin/sh
# changeconf -- edit symlinked files on Knoppix
[ -z "$EDITOR" ] && EDITOR=vi
case "$1" in
  /etc/*)
    if [ -L "$1" ] ; then
      rm -f "$1"
      cp /KNOPPIX/"$1" "$1"
      $EDITOR "$1"
    else
      $EDITOR "$1"
    fi
    ;;
  *)
    echo "only files in /etc allowed"
    ;;
esac


Gruss,
