Done

Yeah, I totally agree.  I have all the pieces in place to make a 32-bit
version of the distro.  I just need to commit the kernel-config to
enable LTT for the 32 bit kernel, and the rest should just be a
one-click re-build.  I will strive to have this ready by the time you
finish testing what I published and are ready to announce.

Done.

That would be cool, though TBH, I have no idea how to do this ;)

LTT makes my life easier and is extremely useful, so its the least I can
do.  Really the credit goes to you and the LTT devs, and the Suse team
that put the build-service/studio together.  All I really did was click
stuff :)
