|
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
Name:
|
|
isofs.di
|
|
|
|
Purpose:
|
|
Records .st_dev and .st_ino of struct stat of the file source in the
|
|
local filesystem. See man 2 stat.
|
|
|
|
Format of Value:
|
|
DEV_LEN | DEV_BYTES | INO_LEN | INO_BYTES
|
|
The _LEN fields comply to ISO 9660 Format section 7.1.1.
|
|
The byte strings begin with the most significant byte.
|
|
|
|
Example:
|
|
Device number 2001, inode number 176343
|
|
{ 2, 7, 209,
|
|
3, 2, 176, 215 }

|
|
|
|
Name:
|
|
isofs.cs
|
|
|
|
Purpose:
|
|
Records the name of the character set that was used as output character
|
|
set when writing the RRIP name tree of the ISO 9660 image. It shall be
|
|
suitable as parameter for function iconv_open(3).
|
|
This attribute shall eventually be attached to the root directory entry
|
|
and be global for the whole image.
|
|
|
|
Format of Value:
|
|
Shall hold the character set name without terminating 0-byte.
|
|
|
|
Example:
|
|
{ 'I', 'S', 'O', '-', '8', '8', '5', '9' , '-', '1' }

|
|
|
|
Name:
|
|
isofs.st
|
|
|
|
Purpose:
|
|
Records a time point at least 1 second before any nodes were added to a
|
|
freshly loaded or created ISO image. Nodes in the image which have
|
|
younger timestamps are suspect to have changed their content during
|
|
image production and might bear inconsistent content.
|
|
The RRIP timestamps have a blind second during which a change after
|
|
node registration would not be recognizable for incremental backups
|
|
which are based in "isofs.di" rather than on content comparison.
|
|
This attribute shall eventually be attached to the root directory entry
|
|
and be global for the whole image.
|
|
|
|
Format of Value:
|
|
Shall hold UTC seconds since 1970 as decimal number string without
|
|
terminating 0-byte.
|
|
|
|
Example:
|
|
{ '1', '2', '3', '8', '7', '4', '2', '2', '9', '6' }
