.PP
If the iso_rr_path of a newly inserted or renamed file leads to an existing
file object in the ISO image, then the following collision handling happens:
.br
If both objects are directories then they get merged by recursively inserting
the subobjects from filesystem into ISO image.
> If other file types collide then the setting of command -overwrite decides.
> Directories may only be deleted by commands -rmdir or -rm_r.
If other file types collide then the setting of command -overwrite decides.

The commands in this section alter the ISO image and not the local filesystem.

> \fB\-overwrite\fR "on"|"off"
Allow or disallow to overwrite existing files in the
ISO image by files with the same user defined name. This is
the RockRidge name and not the plain ISO name.
.br
With setting "off", RR name collisions cause SORRY-events.
Event messages are sent to the info channel "I" which is usually stderr
but may be influenced by command -pkt_output.
Info messages which belong to no event get attributed severity "NOTE".
.TP
\fB\-overwrite\fR "on"|"nondir"|"off"
Allow or disallow to overwrite existing files in the
ISO image by files with the same user defined name.
.br
With setting "off", name collisions cause SORRY-events.
With setting "nondir", only directories are protected by such events, other
existing file types get treated with -rm before the new file gets added.
Setting "on" allows automatic -rm_r. I.e. a non-directory can replace an
existing directory and all its subordinates.
