Hi Wiak!!
In the last post :

fred have persistence like this
short example
mksquashfs temp filesystem.squashfs # will create empty filesystem.squashfs
unsquashfs -f -d /mnt/sdb1 01-filesystem.squashfs
is possible create empty file in weedog
mksquashfs temp 01weedog.sfs # will create empty 01weedog.sfs
and have the same persistence with empty 01weedog.sfs
thanks
