Red Hat Bugzilla – Bug 143261
redundant data in subsequent src rpm packages
Last modified: 2014-03-16 22:51:18 EDT
Description of problem:
SRC packages commonly contain mostly redundant data from revision to
revision. Since kernel is the most commonly looked at and downloaded
src I will start here. The problem may apply to any series of updated
for example all current kernel-2.6.9-1.*_FC3.src.rpm packages
have linux-2.6.9.tar.bz2 (36261440 bytes) in common.
Version-Release number of selected component (if applicable):
I was comparing
Steps to Reproduce:
1. use rpm2cpio and extract the contents of
into their own dir.
2.compare linux-2.6.9.tar.bz2 in both dirs.
$ md5sum *-orig/linux*tar.bz2
Note that the two packages contain ~36MB of bz2 compressed
data that is identical from update to update to update....
I found redundant data to an extent I did not expect.
I did not expect to see this level of redundancy.
good folks reduced one duplication of kernel src with FC3
and recent FC2 updates. There is an opportunity to save
bandwidth and disk space if the linux-2.6.9.tar.bz2
file was packaged in something like kernel-base and distribute
the patches and spec/ build stuff in kernel-update
I suspect that any change to this has non trivial impact on the user
community so I do not wish to rush in....
I have no clear vision of a fix, I just wish to point out this
duplication of bits so a brighter mind than I has the chance to
inventing a way to tidy this up for FC4 or FC5....
speller in subject ;-(
as you mentioned, this affects a wider array of packages than just the
kernel. Assigning to distribution, as we should get a ruling common
across all packages imo.
This is probably not going to get fixed in the current RPM context any
