On my test machine I reproduce it easily : rpm --rebuilddb and if the db
is not detected to be corrupted yet it will be after installing a few
packages (tested again with 2.6.27).
If I do the rebuilddb on a 2.6.17 and then reboot on a recent kernel,
then I can install/uninstall thousands of packages without any
I wanted to try a few things including copying the partition to a file
and trying to reproduce in a vm.
Given how I can reproduce and repair it i can even write a bisecting
script which would basically be an initscript which would do
if on test kernel
- rebuild the db
- install 10 rpm
- remove the 10 rpm
- check the db
- do the good/bad
- reboot onto 2.6.17
else if on 2.6.17
- rebuild the db
- build the kernel
- reboot on test kernel
and let it run :)
All I need is to find some time with nothing more urgent...
