Package: kernel
Version: 2.6.24-etchnhalf.1-amd64
Severity: important


Due to existing bugs I had with UDF in kernel 2.6.18, I use 2.6.24 for 8
days.
With 2.6.18 some file were not copied/created, when my log file was mainly
right.
With 2.6.24 my log file is corrupt.

Some monthes ago, I made one script which copy files to the 33 Gbytes IOMEGA /dev/hda
drive I formatted just before, with udf filesystem, in the same time it
writes the text log file.

Everithing looks nice, but begin of log file contains null bytes till
around offset 0x06e3, when begin of this text file is missing.

The log file is obtained by redirecting stdout.

Disk was formated with:

dd if=/dev/zero of=$DEV bs=512 count=64
/usr/bin/mkudffs --lvid="$LABEL" --vid="$LABEL"  --vsid="$LABEL"
--fsid=$label --media-type=hd  $DEV  &&
mount -i -t udf $DEV $MNT &&
(
echo -e "Role:Archivage hebdomadaire\nnum:Cartouche $label" >
/mnt/iomega/identifiant.txt
umount $DEV
)


Log file is created with the following command:
sauvegarde >$DEST/log/log.log

Function sauvegarde begins with:

presente_date ()
{
  echo -n "          "
  date
}


indente ()
{
  sed -u 's/^/  /g'
}

sauvegarde ()
{
echo -n " A la date du   "; date # FIXME pour process de verification de
date
echo
echo Sauvegarde de $SOURCE vers $DEST
presente_date
cd $SOURCE
echo "i varie dans " *
for i in *
do
        if [ -d $i ]
        then
        (
        if pushd $i
        then
        echo "j varie dans " * &&
        for j in *
        do
            if [ ! -f  $toto ]
            then
                echo " bof"
                continue
            fi

                echo
                echo "** Traitement de  $i/$j"
                presente_date
                if [ $OPTION_CHERCHE_ANTIVIRUS -eq 1 ]
                then

                        echo " Recherche d'antivirus dans $i/$j"
                        clamscan -ri --detect-broken --block-encrypted
--block-max --max-files=2000 --max-space=100M $j
                        presente_date
                else
                        echo " Desactivation de la recherche antivirus,
pour les performances"
                fi

                echo "Archivage de  $i/$j"
                destname=$DEST/data/${i}_"$j"

                (
                echo "$destname"
                if [ -f "$j" ] # guillemets "" pour les noms de fichiers
à espace
                then
                        cp "$j"  $DEST/data/${i}_"$j"
                        #cp "$j"  "$destname"
                else
                        echo " " tar czf $DEST/data/${i}_"$j".tgz $j
                        echo " " tar czf "$destname".tgz $j
                        #tar czf "$destname".tgz $j  ||
                        tar cz  --ignore-failed-read -f
$DEST/data/${i}_"$j".tgz $j ||
                        (

Closing the bug. Compability with Windows is beyond the scope of this bug.
