Re-using an existing REISERFS partition

[philo]

Come (reportedly in a few weeks) Knoppix 7.4.1 and (but probably later) Linux Kernel 3.16, shall I be able to re-use the new REISERFS partition I recently created for Knoppix 7.4.0?

If it can be done, what will be the safest procedure?

The answer maybe in:
http://www.wp-schulz.de/summary/summary-backup.html

Is it still valid? Does it work for a REISERFS overlay or only for the '. img' overlay file smaller than 4GB?

Besides, Werner's script includes both '/home' and '/etc', which may not be a good thing.

You can delete within the function "p_backup()" at position

tar -C /KNOPPIX-DATA/ --exclude=*/Cache/* \
  -vczf /media/$SEL/knx/bufi/$BU_FI ./home/ ./etc/ \
  | awk '{printf "%-78s\r", substr($1, 1, 78)}'

the part "./etc/"

tar -C /KNOPPIX-DATA/ --exclude=*/Cache/* \
  -vczf /media/$SEL/knx/bufi/$BU_FI ./home/ \
  | awk '{printf "%-78s\r", substr($1, 1, 78)}'

and "Backup personal persistent memory" will only save all of '/home'

Does it work for a REISERFS overlay or only for the '. img' overlay

I've created and tested the script with overlay file and with overlay partition. You can see it in the Main part

# if persistent memory in overlay partition
OVL_PART=""
if [ -e /mnt-system/KNOPPIX/knoppix-data.inf ]; then
  OVL_PART=`echo ${INST_PART/1/2}`
fi

Thanks, Werner.

I was reading old copies of your web site and of your script. I am now up to date...
