It is not possible to unmount /mnt/sysimage, because stage2.img is 
copied to the disk for CDROM installs. Then the loopback mount of 
stage2.img is "magically shifted" to the copied image. This is needed to 
be able to swap CD's. It is not really needed vor DVD's. I have no idea 
why remount ro is impossible; stage2.img is cramfs usually and ro...

My workaround for grub installs is the following post scriptlet:
-------------------------------------------------------------------
%post
# install grub loader files in /boot only, if installed by anaconda
if [ `uname -r | grep -c BOOT` -eq 1 ]; then
/sbin/grub-install --just-copy
fi
-------------------------------------------------------------------
This way the second stage loader has plenty of time to really hit the 
disk (since it is not the last package that gets installed), before 
anaconda installs the first stage loader in the MBR (that needs to know 
the pysical postition of the second stage loader on the disk).
