Description of problem:
It appears that anaconda/kickstart wont install the em64t kernel
pakcage (arch=ia32e) on an x86_64 machine. Looking at packages.py
seems to indicate that this is intended behavior, however we have
recieved information from a third party software vendor that their
product is only supported using the em64t kernel. We are left to
installing the em64t kernel ourselves after anaconda has installed all
packages in our standard kickstart list.
Red Hat Enterprise Linux AS (Taroon Update 3)
Red Hat Enterprise Linux
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create an ordered header list with only the ia32e kernel in it
2. kickstart a x86_64 machine using that headerlist.
Actual Results: The install fails
Expected Results: the install should succeed.
Could you please provide details on _how_ it fails?
Also, please note that modifications of install trees in this fashion
can't really be supported (as there's no way for me to know exactly
what changes you've made and the installer does have some subtle
The kernel rpm doesn't install. The result of a headerlist with only
an ia32e kernel on an x86_64 platform is a system with no kernel. It
looks like in hdrlist.py it is rejected based on the checks of base
arch and canonarch around line 366. It is my impression that this
kernel should be supported on x86_64, as it does intall and run. But
inclusion in the header list wont get it to install via kickstart, we
have to use %post to do it.
Oh, right. I put checks in as ia32e optimized packages *could*
possibly not run on x86_64.
Unfortunately, there's not much that can be done in the RHEL3 context
other than installing the package in %post if you have to use the
ia32e kernel on AMD64 boxes.
