Hi all,
I am having problems creating a boot cd under redhat 8.0.
I have gone over doco in RELEASE notes on distribution cds and read lots
of mails on this list in past few days however I can't seem to create a
working boot cd.
My aim is to have a boot cd which can be used to start a network based
kickstart install (kickstart file and OS sourced via nfs).
I have done the following (as root), to create a boot cd image
[root@avalon export]# mkdir last_try
[root@avalon export]# cp -r /mnt/cdrom/isolinux/ /export/last_try/
[root@avalon export]# cd last_try/
[root@avalon export]# chmod u+w isolinux/*
[root@avalon export]# mkisofs -o /export/bootcd3.iso -b isolinux.bin -c
boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T
isolinux
Scanning isolinux
Excluded by match: isolinux/boot.cat
Excluded: isolinux/TRANS.TBL
Size of boot image is 4 sectors -> No emulation
Total translation table size: 2730
Total rockridge attributes bytes: 1322
Total directory bytes: 0
Path table size(bytes): 10
Max brk space used 7000
1824 extents written (3 Mb)
Now mount iso image and see what we have
[root@avalon export]# mount -o loop /export/bootcd3.iso /tmp/cdimage/
[root@avalon export]# ll /tmp/cdimage/
total 3518

When I try and use this cd as a boot cd in another machine it fails. I
can use the distribution cd fine.
When I try and mount this cd on the machine I tried to use it as a boot
cd (after manual install) - I see the following error messages in
/var/log/messages. I am not sure if I should be able to mount this cd?
Is there a way I can verify the boot cd image I am creating?

Any pointers to what is going on here will be much appreciated!
