 Most safe is the default: "any" "discard".

+On all media types it is possible to activate a set of ISOLINUX files
+for booting within the first session. In further sessions an existing boot
+image can get replaced by a new one, but depending on the media type 
+this may have few effect at boot time. See above.
+.br
+The ISOLINUX files have to be added to the ISO image by normal means
+(image loading, -map, -add, ...) and should reside either in ISO image
+directory /isolinux or in /boot/isolinux .
+In that case it suffices to use as bootspec the text "dir=/isolinux" or
+"dir=/boot/isolinux". E.g.:
+.br
+ -boot_image isolinux dir=/boot/isolinux
+.br
+which bundles these individual settings:
+.br
+ -boot_image isolinux bin_path=/boot/isolinux/isolinux.bin
+.br
+ -boot_image isolinux cat_path=/boot/isolinux/boot.cat
+.br
+ -boot_image isolinux load_size=2048
+.br
+bin_path depicts the binary program which is to be started by the BIOS at
+boot time. It is among the files produced by ISOLINUX.
+.br
+An El Torito boot catalog file gets inserted into the ISO image with address
+cat_path at -commit time.
+It is subject to normal -overwrite and -reassure processing if there is already
+a file with the same name.

+The setting of -boot_image will change to "isolinux" "patch" after successful
+writing of a session with -boot_image "isolinux" bootspec.
