+# Poky-tiny is intended to define a tiny Linux system comprised of a
+# Linux kernel tailored to support each specific MACHINE and busybox.
+# Poky-tiny sets some basic policy to ensure a usable system while still
+# keeping the rootfs and kernel image as small as possible.
+#
+# The policies defined are intended to meet the following goals:
+# o Serial consoles only (no framebuffer or VGA console)
+# o Basic support for IPV4 networking
+# o Single user ash shell
+# o Static images (no support for adding packages or libraries later)
+# o Read-only or RAMFS root filesystem
+# o Combined Linux kernel + rootfs in under 4MB
+# o Allow the user to select between eglibc or uclibc with the TCLIBC variable
+#
+# This is currently a partial definition, the following tasks remain:
+# [ ] Integrate linux-yocto-tiny ktype into linux-yocto
+# [ ] Define linux-yocto-tiny configs for all supported BSPs
+# [ ] Drop ldconfig from the installation
+# [ ] Modify the runqemu scripts to work with ext2 parameter:
+#     runqemu qemux86 qemuparams="-nographic" bootparams="console=ttyS0,115200 root=0800" 
+# [ ] Modify busybox to allow for DISTRO_FEATURES-like confiruration
