Setting "off" disables disk filesystem manipulations. This is the
|
||||
default unless the program was started with leafname "osirrox".
|
||||
Elsewise the capability to restore files can be enabled explicitly
|
||||
by -osirrox "on". It can be irrevocably disabled by -osirrox
|
||||
"banned".
|
||||
The setting "blocked" is like "off". But it can only be revoked by
|
||||
setting "unblock", which elsewise is like "on". This can be used
|
||||
to curb command scripts which might use "on" undesiredly.
|
||||
To enable restoring of special files by "device_files" is
|
||||
potentially dangerous. The meaning of the number st_rdev (see man
|
||||
2 stat) depends much on the operating system. Best is to restore

The program name will not be searched in the $PATH directories.

To make this clear, it must contain at least one /-character.

Best is an absolute path.

Example:

xorriso -launch_frontend "$(which xorriso-tcltk)" -stdio -

The frontend program should first send via its standard output:

It should be ready to decode -pkt_output and to react on -mark
