Re: [TCLUG:3310] Modules in devel kernels

[Yao-Pin Kuo <kuo@math.umn.edu>]

Hi
    This is a feature of RedHat 5.1/5.2. Their initscripts( version 3.67
or higher) have been designed such that you get the corresponding modules
directory for every kernel you compiled. However, you need to do something
such that they can work correctly. 
    First, since your system in RedHat 5.1, so your initscripts maybe is
initscripts-3.64. You need to update to initscripts-3.67(you can find it
the update directory of redhat ftp site). 
    Next, you need a file called .rhkmvtag in your /lib/modules/2.1.132/
You can create it by booting the new kernel and doing:
cat /proc/version > /lib/modules/2.1.132/.rhkmvtag
    Finally(this step is not needed for RedHat 5.2 which initscript
already desinged to work with kernel 2.0.* 2.1.* & 2.2.* ), you need to
change /etc/rc.d/rc.sysinit a little bit. Find the line with

mtag=`grep -l "$ktag" /lib/modules/2.0.* ....... 

Change it to 

mtag=`grep -l "$ktag" /lib/modules/*/.rhkmvtag` 2> /dev/null

   After reboot, you new kernel should autoload the modules without
problem.
   Hope this will solve your problem.
