OK, B needs "Requires: A", but cannot be changed.
One way to figger is to add a package D that has
Requires: A B
and change C to do
Requires: A D
rather than
Requires: A B
that might install in ABDC order, and D is harmless.
There is also a (undocumented) --anaconda CLI option
that will "best effort" preserve exactly the order of
the package arguments. By "best effort", I mean that
packages will only be reordered to resolve existing
and necessary dependencies, the original argument order
will be preserved as closely as possible while also
satisfying dependency closure.
It's very hard to say why B is being ordered before A
without real world details (like rpm -Uvv A*.rpm B*.rpm C*.rpm
from whatever A/B/C actually are).
DANG! I tried a package D, but had package A depend on it! I was very close :-) Here is the -ivv spewage for rpm -i A B C: # rpm -ivv A-1-1.i386.rpm B-1-1.i386.rpm C-1-1.i386.rpm D: ============== A-1-1.i386.rpm D: Expected size: 2004 = lead(96)+sigs(180)+pad(4)+data(1724) D: Actual size: 2004 D: A-1-1.i386.rpm: MD5 digest: OK (d3a0250f6ce2739f8af0c80daa1c4e04) D: added binary package [0] D: ============== B-1-1.i386.rpm D: Expected size: 2006 = lead(96)+sigs(180)+pad(4)+data(1726) D: Actual size: 2006 D: B-1-1.i386.rpm: MD5 digest: OK (2d4040f7fb2a686fc778709418059afa) D: added binary package [1] D: ============== C-1-1.i386.rpm D: Expected size: 2017 = lead(96)+sigs(180)+pad(4)+data(1737) D: Actual size: 2017 D: C-1-1.i386.rpm: MD5 digest: OK (ad242ce567dc303181fa8e203cb444a3) D: added binary package [2] D: found 0 source and 3 binary packages D: opening db environment /var/lib/rpm/Packages joinenv D: opening db index /var/lib/rpm/Packages rdonly mode=0x0 D: locked db index /var/lib/rpm/Packages D: ========== +++ A-1-1 i386/linux 0x0 D: opening db index /var/lib/rpm/Depends create mode=0x0 D: opening db index /var/lib/rpm/Basenames rdonly mode=0x0 D: opening db index /var/lib/rpm/Pubkeys rdonly mode=0x0 D: read h# 890 Header sanity check: OK D: ========== DSA pubkey id 219180cddb42a60e D: read h# 4 Header V3 DSA signature: OK, key ID db42a60e D: Requires: /bin/sh YES (db files) D: Requires: /bin/sh YES (cached) D: Requires: /bin/sh YES (cached) D: Requires: rpmlib(CompressedFileNames) <= 3.0.4-1 YES (rpmlib provides) D: Requires: rpmlib(PayloadFilesHavePrefix) <= 4.0-1 YES (rpmlib provides) D: opening db index /var/lib/rpm/Conflictname rdonly mode=0x0 D: ========== +++ B-1-1 i386/linux 0x0 D: Requires: /bin/sh YES (cached) D: Requires: /bin/sh YES (cached) D: Requires: /bin/sh YES (cached) D: Requires: rpmlib(CompressedFileNames) <= 3.0.4-1 YES (cached) D: Requires: rpmlib(PayloadFilesHavePrefix) <= 4.0-1 YES (cached) D: ========== +++ C-1-1 i386/linux 0x0 D: Requires: /bin/sh YES (cached) D: Requires: /bin/sh YES (cached) D: Requires: /bin/sh YES (cached) D: Requires: A YES (added provide) D: Requires: B YES (added provide) D: Requires: rpmlib(CompressedFileNames) <= 3.0.4-1 YES (cached) D: Requires: rpmlib(PayloadFilesHavePrefix) <= 4.0-1 YES (cached) D: closed db index /var/lib/rpm/Pubkeys D: closed db index /var/lib/rpm/Depends D: closed db index /var/lib/rpm/Conflictname D: closed db index /var/lib/rpm/Basenames D: closed db index /var/lib/rpm/Packages D: closed db environment /var/lib/rpm/Packages D: ========== recording tsort relations D: Requires: A YES (added provide) D: ignore package name relation(s) [0] libtermcap -> bash D: ignore package name relation(s) [1] modutils -> vixie-cron D: ignore package name relation(s) [2] ypbind -> yp-tools D: ignore package name relation(s) [3] ghostscript-fonts -> ghostscript D: ignore package name relation(s) [4] libgnomeprint15 -> gnome-print D: ignore package name relation(s) [5] nautilus -> nautilus-mozilla D: ignore package name relation(s) [6] tcl -> postgresql-tcl D: ignore package name relation(s) [7] arts -> kdelibs-sound D: ignore package name relation(s) [8] pango-gtkbeta-devel -> pango-gtkbeta D: ignore package name relation(s) [9] XFree86 -> Mesa D: ignore package name relation(s) [10] compat-glibc -> db2 D: ignore package name relation(s) [11] compat-glibc -> db1 D: ignore package name relation(s) [12] pam -> initscripts D: ignore package name relation(s) [13] initscripts -> sysklogd D: Requires: B YES (added provide) D: ========== tsorting packages (order, #predecessors, #succesors, tree, depth) D: 0 0 1 1 0 +B-1-1 D: 1 0 1 0 0 +A-1-1 D: ========== successors only (4154 bytes) D: 2 2 0 0 1 +C-1-1 D: installing binary packages D: opening db environment /var/lib/rpm/Packages joinenv D: opening db index /var/lib/rpm/Packages create mode=0x42 D: mounted filesystems: D: i dev bsize bavail iavail mount point D: 0 0x0305 4096 385318 735330 / D: 1 0x0002 1024 0 -1 /proc D: 2 0x0007 1024 0 -1 /dev/pts D: 3 0x0008 1024 0 -1 /proc/bus/usb D: 4 0x0302 1024 100878 37792 /boot D: 5 0x0009 4096 63921 63920 /dev/shm D: 6 0x0307 4096 257861 993524 /work D: 7 0x0307 4096 257861 993524 /home D: 8 0x0306 4096 1063329 824991 /work/RHEL-21 D: 9 0x0303 1024 117905 39793 /work/RHEL-21/boot D: 10 0x0301 4096 36852 1244875 /backup D: 11 0x0307 4096 257861 993524 /foo D: 12 0x0307 4096 257861 993524 /foo2 D: 13 0x0307 4096 257861 993524 /var/spool/up2date D: sanity checking 3 elements D: opening db index /var/lib/rpm/Name create mode=0x42 D: computing 6 file fingerprints Preparing packages for installation...

Description of problem: The client wants to install A -> B -> C but has no control over B. Unfortunately, A needs to be installed before B for B to install correctly (B is a vendor-supplied binary-only RPM). With a "requires: A B" in package C, I got the following installation order using RPM command in the shell (note the order of A and B in the command): # rpm -ivh A-1-1.i386.rpm B-1-1.i386.rpm C-1-2.i386.rpm Preparing... ########################################### [100%] 1:B ########################################### [ 33%] 2:A ########################################### [ 67%] 3:C ########################################### [100%] # rpm -ivh C-1-1.i386.rpm A-1-1.i386.rpm B-1-1.i386.rpm Preparing... ########################################### [100%] 1:B ########################################### [ 33%] 2:A ########################################### [ 67%] 3:C ########################################### [100%] When I altered the order of packages A and B on the command line (B before A), the installation order changes to what they are expecting: # rpm -ivh C-1-1.i386.rpm B-1-1.i386.rpm A-1-1.i386.rpm Preparing... ########################################### [100%] 1:A ########################################### [ 33%] 2:B ########################################### [ 67%] 3:C ########################################### [100%] # rpm -ivh B-1-1.i386.rpm A-1-1.i386.rpm C-1-1.i386.rpm Preparing... ########################################### [100%] 1:A ########################################### [ 33%] 2:B ########################################### [ 67%] 3:C ########################################### [100%] With a "requires: A B" in package C, I got the following installation order using up2date (which is what they use for deployment): # up2date C Fetching Obsoletes list for channel: jrfuller-rhel-i386-as-3...

RPM then unwinds the dependency tree and reverse sorts the RPMs. I have not tested this hypothesis thoroughly, however. ---- Question: Assuming that B is a vendor supplied binary-only RPM that cannot be changed, is their any way to affect the sort order so A gets installed before B through the A and/or C spec files (as B is untouchable in the client's situtation)? sure if it will help here: I was passed this URL by the client, but am not sure it is particularly helpful as Prereq == Requires: http://www-eleves-isia.cma.fr/Doc/rpm-4.2.2/tsort Thanks in advance for any help here.
