That's a tad bit of overkill, but I've seen worse solutions.
:) I remember I was a lot stressed some years ago with rpm 4 problems before applying this ugly workaround. Since then evidently I forgot about it :) Now it's great that I can remove it and see rpm work as expected even with heavy installation commands. I also had db integrity problems after full installation (rebuilddb needed) and I think those should be fixed too as well. > > I made this workaround a long time ago (years) to fix problems with rpm 4 > > and just removing this fixed the problem, does it make sense? > > If *not* removing the __db* files "fixes", then yes it makes sense. Yes, I meant removing the 'rm __db*' command, thus keeping the __db* files. > An explanantion consistent with what you appear to be saying is that a > header in an rpmdb was mmap'd directly from the file system.

This explaination sounds good to me for what (little) I know about internal mechanisms. Now I'm trying to build some of the other targets (e.g. the openmamba installation livedvd with 2.2 GB of packages installed) to be sure that the issue is indeed completely resolved. > > Sorry for not finding it myself, afaics rpm 5 is doing its job well! > > NP.

Well, I'll let you know for openmamba-tablet, but there is already a distribution called openmamba-sdk that can be used in chroot with qemu: http://www.openmamba.org/distribution/media/sdk.html?lang=en There is a pointer to the wiki with instructions (http://wiki.openmamba.org/it/index.php/ARM), unfortunately in italian currently, but it should be easy to understand even using an online translator. This distribution, intended for openmamba-for-arm development itself, is a bit outdated but it provides smartpm so it can be automatically upgraded to current packages with "smart upgrade && smart upgrade". > And I should have a OpenMAMBA VM setup in the next couple of days. Fine! I suggest you to install the livecd or livedvd development snapshot.
