The default installed syslinux depends on mtools, we install
syslinux-nomtools too, which has the ext2/3/4 support.

Sorry, I updated this patch a little, it should be:
-m 0755, not 0644.

I merged master-next which contained this patch before seeing this. I've
created a fix for master-next. With this tweak in it. This is the
downside to tweaking branches already in master-next though :(.
Cheers,

Subject: [PATCH] wic: plugin for single ext partition
This is not the final implementatio yet. It is based on a temporary
wrapper script calling extlinux and sudo. The final solution will
call syslinux-nomtools instead of the script.
The wic plugin creates a disk image containig just one ext2/3/4
partition. The target devices are PCs with legacy BIOS. Syslinux
is used as a bootloader.
Creating just one ext partition instead of a fat partiton for boot
and an ext partiton for rootfs solves several issues related to
package based kernel updates on the device.

+# 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.

+# Temporary solution
+# This is a wrapper around extlinux providing similar functionality like syslinux-e2fs will
+# do in future. syslinux-e2fs will be part of future syslinux versions. When this update of
+# syslinux will be released this script will be obsolete.
+#
+# Background:
+# The binary installed on the target device (ldlinux.sys) is the same for syslinux and for
+# extlinux. The difference is the installation procedure. Where extlinux needs a mounted
+# filesystem syslinux-e2fs will work on an image file. In other words, extlinux uses the kernel
+# capabilities to modify the filesystem where syslinux-e2fs will be based on a user space
+# library providing an ext2/3/4 implementation. The purpose of the installer in general is to
+# store the file ldlinux.sys in the first blocks of the filesystem. A regular file cannot be
+# found by mbr.bin since there are not fat or ext algorithm integrated there.
