Is stage2.img still not patched to not eject the CD before the %post?
Or did the process change as far as mounting the media and copying
files to the new environment?
I have a tarball that I need to copy to the destination environment
after the OS install and have been using a patched stage2 file I
whipped up from the 5.1 days and just tried to create an x86_64 image
but the file did not copy over from what I would assume to be the
stage2 not being patched. Can anyone confirm/deny?
Thanks.
For those that will ask, my %post is rather simple:
%post --nochroot
mkdir /mnt/sysimage/var/me
cd /mnt/sysimage/var/me
tar xzvf /mnt/source/me.tar.gz
Sorry, guess I should have given more information....
stage2 is not patched in RHEL 5.3, so it will eject the CD before the
%post is run. This is easily rectified by modifying the dispatch.py file
in stage2.img (see list archives for instructions) and then rebuilding
the stage2.img file.
# Note that the *.img files use the squashfs file system.
# if the tools are not on the system yum install them.
yum -y install squashfs-tools mkisofs cdrecord
# insert install-cd into cdrom
mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
mkdir /home/BlueOnyx
mkdir /home/BlueOnyx/ISOs
mkdir /home/BlueOnyx/BlueOnyx-5.2-20090107
cd /mnt/cdrom
# move the iso to a rw area
tar -c * | tar -C /home/BlueOnyx/BlueOnyx-5.2-20090107 -xf-
cd /home/BlueOnyx/BlueOnyx-5.2-20090107
cp /mnt/cdrom/.discinfo .
umount /mnt/cdrom
# remove the install cd and insert a fresh CD
cd /home/BlueOnyx/BlueOnyx-5.2-20090107/images
unsquashfs stage2.img
cd squashfs-root
vi usr/lib/anaconda/dispatch.py
# find these lines (need to reverse them)
("methodcomplete", doMethodComplete, ),
("dopostaction", doPostAction, ),
#and change to
("dopostaction", doPostAction, ),
("methodcomplete", doMethodComplete, ),
# note with vi you will have to use :w! to write the ro file
# recreate the ram file system:
cd ..
mksquashfs squashfs-root ../../stage2.img
cp ../../stage2.img stage2.img
rm -rf squashfs-root
cd ../
mkisofs -P CentOS -b isolinux/isolinux.bin -c isolinux/boot.cat\
-no-emul-boot -boot-load-size 4 -boot-info-table -r -J -T -o
../ISOs/BlueOnyx-5.2-20090107-1.iso .
cd ../ISOs
# note dev arguement may be different execute 'cdrecord scanbus' to find
dev= info
cdrecord -v dev=5,0,0 BlueOnyx-5.2-20090107-1.iso
You should now have a CD that will run the %post scripts.
There may be typos/erros in the above...
