Live System Persistence

This would be a good time to link to the Debian Live wiki on how to add a "persistent home" to your "poor man's installation".
 , if only one knew which manual to look in

Seems to me to be more flexible to have a file which one can move around, rather than to be bound to a particular partition.
Why? Are you planning on moving around the 1.1 GB squashfs file between partitions, too? 
Actually my just over a year old off-the-shelf 250GB system is beginning to look a bit small when one looks at the 1000 GB off-the-shelf systems coming on offer in the local supermarkets:!: Coming from an 8GB system in danger of cluttering up the disk with unwanted partitions

Seriously, those instructions say the "live-rw" file just has to be at the root of a partition that can be found and read. It's not tied to any particular partition.
Which brings me on to the next puzzling thing ...
# Create an empty ramdisk image
Code:
$ dd if=/dev/null of=live-rw bs=1G seek=1 # for a 1GB sized image file
Zitat:

Code:
$ sudo mount /dev/sda5 px2
$ dd if=/dev/null of=px2/live-rw bs=1G seek=1
dd: memory exhausted
Maybe partition without iso file
Code:
$ dd if=/dev/null of=p8/live-rw bs=1G seek=1
dd: memory exhausted
Looks like it"s trying to create a 1 GB buffer, but have just under 1 GB ram., so maybe 1 MB buffer will succeed. at second best
Code:
$ dd if=/dev/null of=px2/live-rw bs=1M seek=1024

0+0 records out

as sum of all files should exceed 3 GB,
# Make ext2 mountable file system

mke2fs 1.41.12 (17-May-2010)
OS type: Linux
Block size=4096 (log=2)
65536 inodes, 262144 blocks
13107 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=268435456
8 block groups
32768 blocks per group, 32768 fragments per group

Superblock backups stored on blocks:

Writing inode tables: done
Writing superblocks and filesystem accounting information: done
but seems to have gone through OK :So, all I can assume is that this 'dd' creates a file for which space is not allocated, but which grows dynamically up to the max 1 GB.
Question: should I wish to move this file to another partition do I use 'mv' or 'dd'?
