[clug] Wiping a (running) system...

[Andrew Janke]

Thanks all for the various answers and emails about this, in the end I
did a bit of all suggestions:

Step 1: apt-get remove --purge  as much as you can for all running
daemons (ntp, autofs, portmap, etc -- just keep using 'ps -ef' until
they all die).

2: mount tmproot -t tmpfs -o size=1G,nr_inodes=16k /mnt/tmproot

   rsync -aPx / /mnt/tmproot

   pivot_root /mnt/tmproot /mnt/tmproot

3: mount -o remount,ro /

4: "Begin with the threatening"

   for i in 1 2 3; do
      dd if=/dev/zero of=/dev/<device>
   done
