initrd.img module loading

[Peter Eisch]

I'm not sure what your scope is, but maybe this helps...

I had an issue where I needed to forceload drivers where I knew the PCI info
was up to date for the devices we were loading on, so I forceloaded the
drivers in the initrd.img just as the kernel was being installed.  This, of
course, had to be done manually on the install cd's initrd.  But for the
various kernels I ended up with something like this in the spec files for
each platform:

%post bigmem
[ -x /usr/sbin/module_upgrade ] && /usr/sbin/module_upgrade
[ -x /sbin/mkkerneldoth ] && /sbin/mkkerneldoth
if [ -x /sbin/new-kernel-pkg ] ; then
        /sbin/new-kernel-pkg --mkinitrd --depmod --install %{KVERREL}bigmem
fi
/sbin/mkinitrd --preload scsi_mod --preload sd_mod --with cciss \
       /boot/ninitrd-%{KVERREL}bigmem.img %{KVERREL}bigmem
/bin/mv /boot/initrd-%{KVERREL}bigmem.img /boot/oinitrd-%{KVERREL}bigmem.img
/bin/mv /boot/ninitrd-%{KVERREL}bigmem.img /boot/initrd-%{KVERREL}bigmem.img


Maybe do the --preloads in the order you need them loaded.  Hope this helps,

peter
