Hmm,
Lots of pyo pyc duplicates, this should be somehow fixed in python can RPM handle hardlinks iow can an rpm contain a file and hardlink to the file instead of 2 copies of the file?
If rpm can handle hardlinks then this should be fixable preferrably python should just create a hardlink when the pyc and pyo are the same.
About licenses what about a licenses.rpm which gets installed by default which contains most common licenses and which is an obligatory part of the base system. And then just put a ptr to the license in the rpm -qi info? That would also cleanout /usr/share/doc since quite a few dirs there only contain a copy of the GPL / MPL / whatever license

Hello all,
I've found some file duplicates when I browsed through the /usr directory tree in the pristine & complete FC4t2 installation what made me curious how many duplicates are there in total. This is not critical, so please take this as something for your information that some files would better be symlinked/hardlinked in order to not to waste disc space without a point. I know there's sometimes no other way that to duplicate a file, but the statistics I have is IMHO rather interesting:
206405 regular files found, 4149 MiB [5468 MiB] 15797 total dupes, 15705 non-zero sized. 96 MiB [161 MiB], 2.325% [2.951%] wasted by dupes, 13906 symlinks, 5042 hardlinks.
So that 161 MiB is "wasted" physically in the /usr tree, what is about 3% in total from all the files within the /usr hierarchy.
To let this information be somehow worth for the package maintainers, I'm adding a link to the list of all the duplicated files including their sizes and md5 sums and to what package they belong:
http://people.redhat.com/jnovy/files/FC4t2-usr-dupes.gz
This statistics was done by the "slink" utility I wrote some time ago. It's able to replace duplicates with symbolic links to save disc space [EXPERIMENTAL, but seems to work] or just display a statistics about duplicates for a given directory. If you want to give it a try, get it from:
http://people.redhat.com/jnovy/files/slink-0.0.1-pre1.tar.bz2
It's interesting how many GPL "COPYING" clones we have in /usr/share/doc for instance. Unfortunately some of my packages are also affected ;)
