*xattr* (aka EA, or extattr) are pairs of name and value which can be
|
||||
attached to file objects. AAIP is able to represent them and 'xorriso'
|
||||
can record and restore pairs which have names out of the user namespace.
|
||||
I.e. those which begin with "user.", like "user.x" or "user.whatever".
|
||||
can record and restore them.
|
||||
But be aware that pairs with names of non-user namespaces are not
|
||||
necessarily portable between operating systems and not even between
|
||||
filesystems. I.e. only those which begin with "user.", like "user.x"
|
||||
or "user.whatever", can unconditionally be expected to be appropriate on
|
||||
other machines and disks. Processing of other xattr may need
|
||||
administrator privileges.
|
||||
Name has to be a 0 terminated string. Value may be any array of bytes
|
||||
which does not exceed the size of 4095 bytes. xattr processing happens
|
||||
only if it is enabled by command *-xattr*.

If you restore a backup with xattr from non-user namespaces, then

make sure that the target operating system and filesystem know what
|

these attributes mean. Possibly you will need administrator

privileges to record or restore such attributes. At recording

time, xorriso will try to tolerate missing privileges and just
|

record what is readable. But at restore time, missing privileges

will cause failure events.

Command -xattr "user" after command -for_backup excludes non-user
