wat puzels me the most is that if i replace the original /etc/rc5/S49dsl-restore by my simpler variant( it set /opt/.backup_device and than call /usr/sbin/filetool.sh
every thing goes well

following the COMPLETE code of my /etc/rc5/S49dsl-restore :

Code Sample

!/bin/bash

. /etc/init.d/dsl-functions

CMDLINE=$(cat /proc/cmdline)
# DEVICE="$(getbootparam 'restore')"
BACKUP_DEVICE="$(getbootparam 'restore')"
# BACKUP_DEVICE="/dev/hda7"
echo "$BACKUP_DEVICE" > /opt/.backup_device

/usr/sbin/filetool.sh restore noprompt
exit 0

my car /proc/cmdline

Code Sample

ramdisk_size=100000 init=/etc/init lang=us apm=power-off hda=scsi hdb=scsi hdc=scsi hdd=scsi hde=scsi vga=791 nomce fromhd=/dev/hda7 knoppix_dir=dsl-0.8.1 frugal lpd restore=/dev/hda7 mydsl_dir=(/dsl-0.8.0/base /dsl-0.8.0/henk)

filetool.lst

Code Sample

/home/dsl/filetool.lst
/opt/ppp
/opt/bootlocal.sh
/opt/powerdown.sh
/opt/phome.sh
/usr/share/icewm/themes/BlueCurve/default.theme
/opt/mysql
/opt/openoffice
/opt/openoffice1.1.2
/home/dsl/OpenOffice.org1.1.0
/home/dsl/OpenOffice.org1.1.2

<edit>
btw
at startup it says
Restoring backup files from /cdrom
at shutdown
... to /cdrom
</edit

Since I don't run fromhd, it may be a timing issue.

You mod is just really delaying things by storing from cmdline to /opt/.backup_device then reparsing and starting another script that would allow more time to pass.

I will have to setup a test environment to see if I can reproduce this. I will also check with beta testers to see if anyone tested such an environment. But it seems that you have a work-around for your needs for now.

It is indeed interesting to see the many various ways users deploy the system It does make it challenging to test the system in so many ways.

i hardy think its a timing problem
i autoload:
icewm.dsl
spool_lpd_ld.tar.gz = printer settings
amsn.dsl
dsl-aterm.tar.gz
firefox.uci
ImageMagic.dsl
j2re1.4.2.uci
rkhunter.dsl
rox.dsl
tcktk8.3.dsl

this should give more then enough delay.

@Roberts:
please dont waste to many time on this.
i dont give this high priority.
i am happy with the way i have solved it.

No. I like the challenge. I have setup a test machine. Their is an issue with the combination of using fromhd and restore from the same hard drive, same is true for frugal, your mod is specific only to those two combinations. Is it not a timing issue but one of the boot device not represented in /etc/fstab, it is correct in the /etc/mtab which represents devices that have been mounted. That is why your mod works with the fromhd. Your hda7 from /etc/fstab would indicate a mount point of /mnt/hda7 and not /cdrom, whereas using /etc/mtab yields the correct response. To me this indicates a problem inside the knoppix-autconfig whereas the boot device should be represented in /etc/fstab correctly which it is not. It is there I must look for a complete solution.
