Actually live-build is the proper tool for the job, creating a totally 
clean build using debootstrap and a chroot. Refractasnapshot is not 
intended as a replacement for live-build, it is an easy-to-use GUI 
method to produce a working live-image from an existing installation.

Debian's live-config mechanism does not support TDE 
(live-session-specific configs for autologin, kpersonalizer, locale, 
language, sudo...) however does support additional custom scripts like 
live-config-trinity.

Of course whatever installer you use must reverse some of those edits 
(tdmrc and others).

RE Sid: Slavek's Jessie binaries work fine here at the moment. In the 
past the crucial ones depended on a specific binutils version which 
broke them for Sid.
