Hi David!

I found that "lang=de locales=de_DE.UTF-8" thingie when I went through your code - well, after I patched the default language to de_DE. I decided it's better to keep the locals of my audience as default and did not revert the patches :)

/etc/snapshotid: Found that, too. Uncommenting exegnu-installer line 36 solved that problem.

Other tweaks I did was to keep autologin (exegnu-installer), basicly got rid of /etc/exegnu/skel (does not fit into my intended usecase) and placed all the defaults in /etc/skel. I remember I did some patching on the way for post-install changes of the homedirectory when the new username does not match the old - I hope i did not patch that out later ..

I moved /tmp and /var/tmp to tmpfs, for the sake of flash livetime. I was thinking of doing that for /var/log, too, but then .. well, maybe later.

Nik
