From: jean <jean.sorgemoel at laposte.net>
default generate iso with grub bootloader
you can select isolinux bootloader
detail : (module fs/iso9660)
option to select bootloader (grub/isolinux)
file(s) bootloader configuration
option to copy file(s) on iso (only for isolinux)
option to create iso with long filenames (Joliet format)
option to create iso with POSIX file system (file mode, uid, gid, ...)
define volume label
define parameter input charset
can use initramfs (if activate), also cpio (like initrd)
