A "LiveCD" will not be easy to create. The %{l_prefix}/var directory
must be writable. Because nobody I know of has ever tried running
OpenPKG from a read-only media other places might be found that need
write access - or fixing ;-)
As far as I know a complete Kolab install takes something like 500MB disk
space not including the RPMs. Too much for the average memory filesystem.
My suggestion for a (Knoppix-like) self contained bootable CD:
- do a union/translucent mount
drawback: hard to create
My suggestion for a mount-into-existing-system CD:
- create binary RPMs
- let the user to create a symlink to a huge disk space
- boostrap/install using binary RPMs (maybe using obmtool)
drawback: existing system is touched, see "entry-points" below

/etc/openpkg is new to OpenPKG 2.0

An empty prefix, won't work because many code pathes within various
OpenPKG scriptlets change the working directory and assume access to
%{l_prefix} through an absolute path. Hashpling aka shebang (#!/...
at the top of a script) accept relative pathes but they will fail if
not executed from within the proper directory. For the same reasons, a
prefix with a relative path won't work, too.
