I am trying to copy /home/user from one RH9 machine to another RH9 machine, using a CDR; but the files and directories lose their permissions. How should this be done properly, please?
WHAT I'VE DONE SO FAR: I used a CDR, and syntax from RH8 Bible by Negus, p471.
mkisofs -o /var/tmp/user.cd /home/user cdrecord -v speed=10 dev=0,0,0 -data /var/tmp/user.cd
WHAT HAPPENS: On copying the files and directories into the new /home/user directory, icons are labeled as user not having necessary permissions. e.g., /evolution has changed from 700 to 555, /stuff has changed from 755 to 555, and a .html file has changed from 664 to 555.
WHAT I THINK THE PROBLEM IS: A CD is an archive media, and so it's something in the way I made the CD,-
but what should have been the way to do this, please?
Thanks in advance, Chris
Use a tar archive - you can specify it to keep permissions. You're correct - writing onto CD kills some permissions due to the way ISO/Joliet read-only is applied to the files.
Same happens when I use windows to back up a directory shared using samba - when the modified bit is set during the backup, the linux file loses it's linux permissions. Highly annoying.
'man tar' should give you what you need.
