Is it possible to create a 'save' file without actually going through the shutdown process?

Assuming you want the pupsave on hda1 and that hda1 is mounted

Code:
dd if=/dev/zero of=/mnt/hda1/pup_save.2fs bs=1k count=50000
mke2fs -q -m 0 -F /mnt/hda1/pup_save.2fs


this makes you an empty 50MB pupsave which should be used automatically on your next boot

Thanks Trapster. Not quite what I was after. I was wondering if a save file could be created and mounted for use 'on the fly', but I guess not as setting up the file system the first time has to be done during a boot process.

You could do as trapster says and then copy the contents of pup_rw to it.
This answers 'how to create a save file'
But mounting on the fly is something else.
So you would boot with a pfix=ram state and once booted mount that save file?
It should be mounted on /initrd/pup_rw then, if ever possible.
