Cheers Nik,

I see you (mostly) worked out your remaster issues yourself! Well done, 
and thanks, because you also raised a few issues with the default exegnu 
image that need sorting but I had missed. It needs to work 
out-of-the-box with refractasnapshot.

Re language: The correct way to set language is with a boot parameter on 
cmdline, e.g. lang=de (parsed in live-config script 1066-trinity-lang) 
OR the Debian way, locales=de_DE.UTF-8 keyboard-layouts=de .. no need to 
edit those scripts. It only defaults to en_US if nothing is specified or 
if it is unspported. Of course the appropriate TDE language pack should 
be installed, e.g.tde-i18n-de-trinity. Which it isn't on the default 
iso, multiple language packs would make the iso very large!

The exegnu installer needs patching to show "clone" mode properly. It's 
looking for a file "/etc/snapshot-id", from a previous experimental 
snapshot version no longer in use. That should in turn fix the skel 
issue for a snapshot installation.

Thanks for identifying 1067-exegnu-userdefaults, line 48 .. I expect 
that was once correct but maybe got changed in ascii/beowulf..

Not sure what you mean by modifications to the various 
refracta/live/exegnu-packages .. if you mean package lists, you would 
need to generate a new one before running refractasnapshot e.g.
dpkg -l|egrep "^ii|^hi"|awk '{print $2 " " $3}' |column -t > pacckages.txt

and place it manually in /live of your snapshot build directory before 
you build the iso..
