Yum update asmlib workaround

Question

Hello,
We would like some help with our following issue.
In short:
while trying to install/update asmlib with oracleasm-2.6.18-348.el5-2.0.5-1.el5.rpm
a directory-structure containing these modules  was expected:
-/lib/modules/2.6.18-348.el5/weak-updates/usm/oracleadvm.ko
-/lib/modules/2.6.18-348.el5/weak-updates/usm/oracleoks.ko
-/lib/modules/2.6.18-348.el5/weak-updates/usm/oracleacfs.ko
For we didn''t have these modules at install time the install failed.
We found a way of bypassing the problem:
We link the 3 modules from the oracle 11.2.0 install environment to the expected /lib/modules/2.6.18-348.el5/weak-updates/usm/modulename
Dillema: for we are Linux-system-managers we are not know for certain whether this is the appropriate thing to do.
Maybe someone can shed a light on this matter?
In our update-script we do:
# Determine Oracle ACFS/ADVM/OKS kernel module location   
oracleacfs=$(find /app -name oracleacfs.ko -type f | grep -v i6 | grep -v xen | grep -v SLES | tail -1)   
returns:   
echo $oracleacfs /app/grid/product/11.2.0/install/usm/EL5/x86_64/2.6.18-8/2.6.18-8.el5-x86_64/bin/oracleacfs.ko   
oracleadvm=$(find /app -name oracleadvm.ko -type f | grep -v i6 | grep -v xen | grep -v SLES | tail -1)   
oracleoks=$(find /app -name oracleoks.ko -type f | grep -v i6 | grep -v xen | grep -v SLES | tail -1)   
#create if not present and fill the kernel-specific usm-directory:   
# Process all installed kernels   
for i in $(rpm -q kernel)   
do     
kernel_version=$(echo ${i}|cut -d '-' -f2,3,4,5)     
# Check softlinks for Oracle ACFS/ADVM/OKS kernel modules     
      if [[ ! -e /lib/modules/${kernel_version}/weak-updates/usm/oracleacfs.ko &&           
      ! -e /lib/modules/${kernel_version}/weak-updates/usm/oracleadvm.ko &&           
      ! -e /lib/modules/${kernel_version}/weak-updates/usm/oracleoks.ko ]]     
then       
     echo "Creating softlinks for Oracle ACFS/ADVM/OKS kernel modules; ${kernel_version}" | tee -a ${LOGFILE}      
       if [[ ! -e  /lib/modules/${kernel_version}/weak-updates/usm ]]       
     then         
          mkdir -p /lib/modules/${kernel_version}/weak-updates/usm       
     fi       
      ln -s $oracleacfs /lib/modules/${kernel_version}/weak-updates/usm/oracleacfs.ko       
      ln -s $oracleadvm /lib/modules/${kernel_version}/weak-updates/usm/oracleadvm.ko       
      ln -s $oracleoks  /lib/modules/${kernel_version}/weak-updates/usm/oracleoks.ko     
     else       
      if [[ -e /lib/modules/${kernel_version}/weak-updates/usm/oracleacfs.ko &&             
      -e /lib/modules/${kernel_version}/weak-updates/usm/oracleadvm.ko &&             
      -e /lib/modules/${kernel_version}/weak-updates/usm/oracleoks.ko ]]       
then #
Any help is appreciated.

Check the following:

# wget http://oss.oracle.com/projects/oracleasm/dist/files/RPMS/rhel5/amd64/2.0.5/2.6.18-348.6.1.el5/oracleasm-2.6.18-348.6.1.el5-2.0.5-1.el5.x86_64.rpm
oracleasm-2.6.18-348.6.1.el5-2.0.5-1.el5.x86_64.rpm” saved [25455/25455]
# rpm2cpio oracleasm-2.6.18-348.6.1.el5-2.0.5-1.el5.x86_64.rpm | cpio -idmv
./lib/modules/2.6.18-348.6.1.el5/kernel/drivers/addon/oracleasm
./lib/modules/2.6.18-348.6.1.el5/kernel/drivers/addon/oracleasm/oracleasm.ko
The above shows to me that the oracleasm package does not contain any installation script or ACFS module.
