+# DESCRIPTION
+# This plugin creates a disk image containing a bootable root partition with
+# syslinux installed. The filesystem is ext2/3/4, no extra boot partition is
+# required.
+#
+# Example kickstart file:
+# part / --source rootfs-pcbios-ext --ondisk sda --fstype=ext4 --label rootfs --align 1024
+# bootloader --timeout=0 --append="rootwait rootfstype=ext4" --source rootfs-pcbios-ext
+#
+# The first line generates a root file system including a syslinux.cfg file
+# The "--source rootfs-pcbios-ext" in the second line triggers the ldlinux.sys
+# installation into the image.
+#
