OK, I had to do it again (disk transplant from a i586 to a i686)...

I posted this to the linux.redhat.com newsgroup and didn't get a reply.
I now need to apply some updates, but can't do things automagically with
yum because of this problem (I'll have to update some packages manually
with 'rpm --ignore-arch ...', which is a real PITA). I did a google
search and cannot find any documentation on how to fix this. Do I
really need to do a fresh re-install? Arg!!!

My K6-500 system seems to have died (I guessing something with the
motherboard -- the system started kernel panicing somewhere in i8042.c
(keyboard / PS/2 ports?). I transplanted the disks, disk controller,
server box. I upgraded the kernel (to a .i686 kernel), and
re-installed glibc (.i686) and openssl (.i686). RPM still believes
this is a i586 box. There is *some magic* somewhere in the RPM
database / configuration that remembers the arch. How do I fix this
short of a clean re-install from scratch -- I really, really don't want
to have to do this, since it means I need to hunt down all of the extra
stuff I've installed and redo ALL of the configuration files -- this
could take MONTHS of fussing with, just to change one digit (one byte!)
somewhere in RPM's database or configuration. It really can't be that
hard to fix!

--------------------
Where does RPM's 'ARCHITECTURE AND OS' information live? What file do I
need to edit to change it? It is none of the *listed* macrofiles -- I've
already checked them.
Has nobody (but me) *ever* done a disk transplant from a i586 to a
i686? This is the second time I've done this [this year] -- earlier
this year I transplanted the disk from a i586 laptop to a i686 laptop.
In the past I have done system upgrades -- I replaced a i486
motherboard with a i586 motherboard in the past -- really old days --
before people bothered much with arch=specific kernels and and such (RH
5.2 - 2.0.x kernel) and had no problems.

edit /etc/rpm/platform

make sure it says i686, not i586 in there.


then do your updates w/yum. It, in theory, should be able to get you to
the proper archs.

It works!!! Thanks.

Where is this documented?
