For some odd reason (at least I couldn't find an explanation to this,

not overwritten.
For two packages with the same name, but different architectures -- the non-ELF
files must be identical (or different file names in each package.)
The ELF files are identified by type and there is a resolution mechanism within
RPM to determine which is the 'preferred' version.
We do NOT have the resolution mechanism set, so the first package installed
'wins'. So if you do two packages in two separate transactions, the first
version installed will be kept. If you do it in one transaction, then I believe
it ends up being the last version [or maybe it's random due to sort order?]
There is a Yocto Project defect to configure the RPM multilib settings, but so
far it's just sat there, as nobody has either needed it -- or cared enough to
implement it. The reality is installed two packages with the same /bin, /sbin
binaries is rare these days.. it's much more useful to install the libraries.
The code you have below may turn out to be a performance improvement.. (each
smart/rpm transaction takes setup and cleanup time, so multiple transactions are
slower then one larger transaction.) But it's likely not fixing the actual
problem you have.
# The default transaction color. This value is a set of bits to
# determine file and dependency affinity for this arch.
# 0 uncolored (i.e. use only arch as install hint)
# 1 Elf32 permitted
# 2 Elf64 permitted
# 4 MIPS reserved
%_transaction_color 3
(4 BTW is MIPS64 - n32)
_transaction_color of 3 indicates we allow Elf32 and Elf64 to be installed..
There is a second item:
_prefer_color that is used to define which item should be installed when there
is that ELF conflict. The numbers above follow there as well. By default I
believe it sets itself to '2' when doing a single transaction installed,
preferring Elf64.
--Mark
This commit restores the functionality to the original one, before
migrating to python: feed all the packages to smart, apart from attempt
only ones which are installed separately.
