Yup, I know what is broken , please, I ask you, do your homework before you do stuff . . . here, the very first line ! on the Debian page at Remastersys !
How do you use it?
There are some pre-requisites for the debian version that aren't there for the Ubuntu version.
You should install squashfs-modules for your kernel and either aufs-modules or unionfs-modules before you install remastersys.
Did you upgrade to the liquorix kernel again ?
If your kernel doesn't have the squashfs-modules and either the aufs-modules or unionfs-modules, you MUST use a different kernel. No ifs ands or buts about it.
What
you should have read instead of me !
