I can think of a couple of ways to do it. You are probably going to
want to set up a full 32 bit directory tree off some directory in /.
(I would uses something like 32_bit_tree.) You then have a couple of
options. Probably the simplest is to use the --root=<directory name>
option for all your 32 bit RPM operations. (The first things, after
creating the tree, is to run "rpm --root=<directory name> --initdb"
to create an empty database for RPM to work on. (It is a good idea
to back up your current RPM database first, in case you make a mistake!)
You also have the option of using chroot to change to your 32 bit
tree. I have never done thing on a 64 bit system, so I do not know
for sure that it will work. It should, as long as RPM does not get
confused and install the 64 bit RPMs. If you try this, let us know
how it works for future reference.
In ether case, one of the first things you will want to set up after
creating your directory tree is the 32 bit /etc, /bin, /lib, and
/sbin directories. You can not use chroot before you use the 64 bit
version of RPM to install enough of the system for rpm to run.
It has been a long time sense I have done this, and that was a
second 32 bit tree on a 32 bit system. So I am probably forgetting
something. I did find it is a lot easier to have a separate
partition for the 32 bit version, and do a bare-bones install to it.
But it can be done this way.
Do not meddle in the affairs of dragons,
for thou art crunchy and taste good with Ketchup!
