We don't need to redistribute the original files. We could make up a way
to have "patches" for SRPMs.
What you do when changing an SRPM is usually the following:
0. download the SRPM
1. extract the SRPM
2. change the SPEC
3. change/add/remove patches and other Sources
4. extract the included tarballs if they need to be changed
5. apply changes to the tarball content
6. repackage the tarballs
7. repackage the SRPM
Afaict this is all scriptable.
0. wget http://whatever.url/the/file/is/located/at.src.rpm
1. rpm -i whatever.src.rpm
2. cd SPEC && patch < spec-changes.patch; cd ..
3. cd SOURCES && patch < source-changes.patch; tar xf sources.tar; cd ..
4. gzip -cd whatever-1.2.3.tgz | tar xCf /tmp -
5. cd /tmp/whatever-1.2.3 && patch < tarball.patch; tar xf tarball.tar
6. cd /tmp tar cf - whatever-1.2.3 | gzip -c9 > whatever-1.2.3.tgz
7. rpmbuild --nodeps -bs whatever.spec
I'll admit that it isn't that simple, but we could have a system to keep
"SRPM patches" around and as these won't contain RH trademarked stuff it
The to-be-patched SRPMs can be fetched by anyone from the original
source which is also ok.
As you might have noticed I'm suggesting to unpack tarballs into
existing directories. This is to overwrite and replace existing and
"offending" RH stuff. Files that should be removed can simply be
overwritten with 0-byte files (I guess nobody can sue us for a filename
in a tarball)
If something like this is appreciated I could write example-scripts to
do the work.
btw. please CC responses to me (I don't want to take this off-list, I'm
just not reading regularly enough to catch responses in time otherwise).
