Hi,
The OBI has taken the step from [pre]version 0.7 to version 1.0:
1. The dialogue has been improved by using screens made with the linux
program dialog. It means a menu style similar to that of the alternate
installer and the mini.iso. See the attached pictures. Feedback from
several persons made me understand, that the previous interface was not
good enough for the majority of computer users, so this was necessary.
There are still some rough edges, but the basic usage should be easier
and more appealing now. And in the near future I intend to remove the
rough edges (that I am aware of).
2. The compression of the dd-image files and the tarballs is improved.
The original compression was using gzip. It is still available, but now
xz compression is also available, and xz compression is more than 20%
more efficient, often 30% (meaning that the size of the compressed file
is 20-30% smaller than a gzipped file). xz is slower and needs more
memory, but not too much. During a test with low RAM, 128 MB, extracting
the tarball with xz used 62 MB while extracting with gzip used 49 GB.
Downloading is usually the bottleneck, so small files are preferred.
The default compression for making an own tarball is using gzip. In the
present version 1.0, you must run mktbl from the bash shell to create an
xz tarball, which is one of the rough edges.
