Aha. Thanks for explaining that.


Whether that's a sane thing to do is another question.

It's dangerous / not sane IMHO.

I am curious how you would propose to resolve that taking into
account all existing packages and this detail that people making
original packages may be often unaware of the issue and even if they
are they may not have suitable installations for testing.  Multiply
that by 'extras', external repositories, and so on.  If you will get
strict here then resulting pains will surely far exceed your worst
current hiccups.

The worst case I had was where some key arch-dependent glibc files
got clobbered (FCtest days) - rescue CD time.

AFAICT dependencies are really "swallowed" during an installation if
files in question are the same - which is easy to test.  At least if
the whole concept is not buggy It appears that you were bitten by
something else or you run into some traps in testing but that what
testing is for.

If it only "swallowed" identical files I wouldn't mind either but consider this:
[root@linox01 xxx]# rpm -q tcsh
package tcsh is not installed
[root@linox01 xxx]# rpm -Uvh tcsh-6.13-9.i386.rpm tcsh-6.13-9.x86_64.rpm
Preparing... ########################################### [100%] 1:tcsh ########################################### [ 50%] 2:tcsh ########################################### [100%]
[root@linox01 xxx]# file /bin/tcsh
/bin/tcsh: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), stripped

Notice the lack of any warnings or complaints from rpm. In fact it doesn't even need to be in the same transaction apparently:

[root@linox01 xxx]# rpm -e --allmatches --nodeps tcsh
[root@linox01 xxx]# rpm -ivh tcsh-6.13-9.x86_64.rpm
Preparing... ########################################### [100%] 1:tcsh ########################################### [100%]
[root@linox01 xxx]# rpm -ivh tcsh-6.13-9.i386.rpm
Preparing... ########################################### [100%] 1:tcsh ########################################### [100%]
[root@linox01 xxx]# file /bin/tcsh
/bin/tcsh: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), stripped

..and again zero complaints from rpm, the 32bit version of tcsh only exists in rpmdb in reality.
