give a parameter or string by default to the prompt after booting from CD/DVD
Dear All,
I am trying to give a parameter or string by default to the prompt after booting from CD/DVD after modifying isolinux.cfg file
For this I am able to successfully alter the boot.iso present in RHEL+CENTOS DVDs using the below command
mkisofs -o /new.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -J -R -V disks .
But, when I am trying to alter the Netbackup BMR iso file it does not has boot.cat file and also giving me below errors.
These are the contents of iso file
Code:
$ ls -lrth
total 96K
drwxr-xr-x 9 vikas vikas 4.0K Mar 8 18:17 etc

And thes are the contents of isolinux folder, please note there is no boot.cat file here.

$ ls -l isolinux/

I am unable to dig this error.
Code:
$ /usr/bin/mkisofs -o $HOME/new.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -J -R -V disks .
INFO: UTF-8 character encoding detected by locale settings.
Assuming UTF-8 encoded filenames on source filesystem,
use -input-charset to override.
Using RR_MO000 for /rr_moved (rr_moved)
/usr/bin/mkisofs: Error: '(NULL POINTER)' and './rr_moved' have the same Rock Ridge name 'rr_moved'.
/usr/bin/mkisofs: Unable to sort directory
If I remove " rr_moved" directory and does not include " -c isolinux/boot.cat" in my mkisofs command, a bootable iso is created but it is around 40 MB less than the original iso image.
Any idea how to get through this error ? |
