Debugging rpm package installation order

Thu Aug 8 09:56:10 CEST 2013

Hi,

I am building a system image for a PLD-based distribution using poldek.
It used to work well until I have upgraded my RPM from 4.5 to 5.4.12.
Now the packages are installed in wrong order, %post scripts fail and
the whole image build fails.

poldek --verify=order gives a reasonable order:

No loops -- OK
Installation order:
0. FHS-2.3-35.aos1.i686
1. filesystem-4.0-11.aos1.i686
2. ldconfig-2.15-10.aos1.i686
3. libsepol-2.1.4-1.aos1.i686
4. libselinux-2.1.9-2.aos1.i686
5. setup-2.7.1-1.aos2.i686
6. pdksh-5.2.14-56.aos2.i686
7. glibc-2.15-10.aos1.i686
8. glibc-libcrypt-2.15-10.aos1.i686
9. SysVinit-tools-2.88-7.aos1.i686
10. zlib-1.2.7-1.aos1.i686
11. module-init-tools-3.16-4.aos1.i686
12. alsa-lib-1.0.25-1.aos1.i686
13. popt-1.16-1.aos1.i686
14. attr-2.4.46-1.aos1.i686
15. gmp-5.0.5-1.aos1.i686
16. libcap-libs-2.22-1.aos1.i686
17. libxcrypt-3.0.2-2.aos1.i686
18. make-3.81-1.aos2.i686
19. mawk-1.3.3-32.aos2.i686
20. cracklib-2.8.3-0.2.aos2.i686
21. cracklib-dicts-2.8.3-0.2.aos2.i686
22. gdbm-1.10-1.aos1.i686
23. sed-4.2.1-2.aos1.i686
24. pam-libs-1.1.5-7.aos2.i686
25. pam-1.1.5-7.aos2.i686
26. coreutils-8.16-1.aos1.i686
[...]
64. util-linux-2.21.1-1.aos4.i686
65. rc-scripts-0.4.5.4-2.aos1.i686

But the packages are installed in wrong order by rpm, so e.g. rc-scripts
%post fails, because rc-scripts is installed long before coreutils.

I guess this could be caused by some dependency problems in my packages.
Poldek reports no loops. RPM 4.5 used to generate useful loop warnings
in case a dependency loop was detected (the message stated exactly what
packages are in the loop). The new RPM reports loops only when debug
output is enabled (-vv), but I am not able to get any useful
information from those messages:

How should I read those? Where is the loop?
