mkisofs rebuild TinyCore-10.0.iso

[midas007]

Here is my study to rebuild the iso .

Code: [Select]

sudo mount -o loop TinyCore-10.0.iso  iso_contents
mkdir iso_contents_copy
rsync -a -H iso_contents/ iso_contents_copy
sudo umount iso_contents
<do someting modify core.gz>
mkisofs -o ReBuildTinyCore-10.0.iso -J -R -hfs iso_contents_copy/
seems everything good . but myvbox can't bootup from ReBuildTinyCore-10.0.iso
Of course TinyCore-10.0.iso working fine !

Can some one share any idea can make the vbox can bootup the rebuild iso directly ?


PS: update the isoinfo

Code: [Select]

isoinfo -d -i ./TinyCore-10.0.iso

Hi, midas007!

Try to look into the Corebook, section 11.3 Packing.
Good luck!

Hi midas007
Please use  Code Tags  when posting commands and responses seen in a terminal. To use  Code Tags  click on the  #  icon
above the reply box and paste your text between the  Code Tags  as shown in this example:

It will appear like this in your post:

Hi midas007
Take a look where it says  Creating ISO file  over here:
http://forum.tinycorelinux.net/index.php/topic,21921.msg137135.html#msg137135
The  \  character in that example means the next line is still part of the same command.

Thank you very much Rich.
Finally it's work by using ReBuildTinyCore-10.0.iso directly @ VBOX.
But when using "dd" to exactly write to USB disk to bootup.
It still work only on TinyCore-10.0.iso but not my ReBuildTinyCore-10.0.iso


P.S1 :  I use extract core.gz command as below

isoinfo -i ${isoimg} -x /BOOT/CORE.GZ\;1 > ${isoimg}.WorkingTree/core_x.gz
zcat ../core_x.gz | fakeroot -s ../initrd.fakeroot cpio -i -H newc -d

P.S2 : compress back to core back again by command as below.

sudo find | fakeroot -i ../initrd.fakeroot cpio -o -H newc | gzip -9 > ../core_SVN_XXX.gz

P.S3 : my iso command.

Code: [Select]

mkdir iso_contents
mkdir iso_contents_copy
sudo mount -o loop TinyCore-10.0.iso iso_contents
rsync -a -H iso_contents/ iso_contents_copy
sudo umount iso_contents
sudo rm iso_contents_copy/boot/isolinux/isolinux.cfg
sudo rm iso_contents_copy/boot/core.gz
sudo cp isolinux.cfg iso_contents_copy/boot/isolinux
sudo cp core_SVN_$SVN_REV.gz iso_contents_copy/boot/
cd iso_contents_copy
sudo mkisofs -r -l -J -R -no-emul-boot -V TC-custom -boot-load-size 4 -boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -quiet -r -o ../linux_boot_$SVN_DATE\_V$SVN_REV.iso ./
cd ..
sudo rm iso_contents -r
sudo rm iso_contents_copy -r
ls linux_boot_$SVN_DATE\_V$SVN_REV.iso -l

If you want to dd an iso to an usb stick, you also have to run isohybrid on it.
