Hi all. I have been working on a new build script to create a bootable cd from flashboot. I have tried not to interfere with existing code and the only change/addition is in list.largekernel where the directory /cd is added as a mount point for the cd. The rest is in done in build_livecd.sh and with two new files (initial-conf/boot.conf.iso and initial-conf/fstab.initial.iso). Backups can be stored to USB memories but I do have some issues with certain types of memory sticks but that is more of a compatibility/driver issue with OpenBSD i think.
Anyway, please take a look at it and tell me what You think. Regards Niclas Rosell

+Creating bootable cd
+--------------------
+
+To create an iso image suitable for booting and running flashboot
+on a x86 PC, first read the build instructions above. Step 1 and 2
+must be successfull and in step 3 use the build-livecd.sh script with
+the GENERIC-RD kernel config.
+
+ # ./build-livecd.sh GENERIC-RD
+
+The build-live_cd.sh script will create the directory live_cd before
+creating the image. Everything in this directory will be included on the
+cd. The files cdbr, cdboot etc/boot.conf is required for booting. To
+customize the cd with additional data, create the directory live_cd in
+advance and populate with data and modify rc.{init|more} as needed.
+The build-livecd.sh will use the default flashboot config files
+and make modifications prior to ramdisk creation. Any customisation to
+ramdisk setup should be done by editing build-livecd.sh.
+
+If everything worked then you should find a new iso image in
+obj/live_cd{version}.iso. Without any customisation the iso is roughly
+9MB in size. Finally... burn the iso with your favorite cd burning
+program.
