If you read the man page for mkisofs, you will understand why all files are 
owned 
by root on your CD.

Hi Joerg,

Tks for your advice.

 Try man mkisofs to learn how to correctly use RR.

I went through man mkisofs(8) and came to following conclusion.

If the original mode of directories and files are;
directory=0664
file=0664
owner and group=satimis:satimis

To preserve the original state after burning, the command line will be;

# mkisofs -o cd.iso -r -uid satimis -gid satimis -dir-mode 0664
-file-mode 0664 -new-dir-mode 0664 /path/to/data 

If I'm wrong please correct me.

I'm not clear of -z option, what does it mean transparently compressed
file and the resulting disks are only transparently readable'?

TIA

About RockRidge

Hi folks,

About RockRidge
==

I have been searching around on man mkzftree, man mkisofs, etc.
including googling around for examples in applying -ZF options to
compress the directories and files, to create ISO image and to burn as
well as to decompress the directories and files.  But I could not find
them.  Could you please shed me some light. Pointers would be
appreciated.

My purpose using RockRidge is retaining oringal ownership and
permission of data to solve following problem;

I burnt /home/ of a FC3 box on CDs. /home/ was on its own partition.
Then running LFS LiveCD I copied the CDs on a partition of a new HD
which has 6 partitions. I'm prepared to build LFS--BLFS on the new HD
applying LFS LiveCD as host. Later I discovered all data after
transferred from the CDs onto the partitions became read only and
permission changed from User to Root. Now I need to reinstate their
original state, i.e. Write/Read, User, etc. Either I have to do it
manually or to re-burn the data from /home/ of the FC3 box onto the
CDs.

Could you folks on the List please shed me some light. TIA

B.R.
SL
