It is subject to normal \-overwrite and \-reassure processing if there is already
a file with the same name.
The catalog lists the boot images and is read by the boot facility to choose
one of the boot images. But it is not necessary that it appears in the
directory tree at all. One may hide it in all trees by \fBcat_hidden=on\fR.
Other possible values are "iso_rr", "joliet", "hfsplus", and the default "off".
The timestamps of the boot catalog file are refreshed at commit time.
Command \-volume_date "uuid" can be used to set their value.
