Re: xorriso, create an iso archive from a directory which has NTFS ACLs/xattr

[Kristaps Esterliņš]

Dear Thomas,

I apologize for the late reply. 

The goal I wanted to achieve was to create an iso archive with data from a samba share which uses NTFS ACLs. 

To overcome this first issue, I list the permissions with getfacl and then write the data to a separate file which then is included in the iso.

Here is the script I am using. 

xorriso -joliet on \

  -compliance joliet_long_names \

  -compliance joliet_long_paths \

  -abort_on FAILURE \

  -md5 all \

  -hardlinks on \

  -volid BACKUP_19102022 \

  -disk_dev_ino on \

  -dev /srv/archive/backup_19102022.iso \

  -update_r "$SOURCE_DIR" / \

  -update_r /tmp/.directory.acl .directory.acl \

  -commit \

  -toc \

  -check_md5 FAILURE

Is "-update_r" the correct way to add files, folders and subdirectories or should I switch to "-add" ? I do not need to update the iso file, it will be created once per X days and the stored in a different location.

Thanks again!

Dear Thomas,

No worries. Thank you for your help and suggestions!

I will try to test that today and report back.

Hi,

"R" and "F" are too near together on my keyboard. I ment to write:

  [...] getfacl(1) or ./acl_test [...]


(And then i messed up the threading again, by replying to the older mail.)


Have a nice day :)
