-Eeepc "fastinit" reimplementations
-----------------------------------
+Finit is a reimplementation of the Eeepc "fastinit" program based on its
+system calls with gaps filled with frog DNA.
 
-finit.c is a reimplementation of the Asus Eeepc fastinit program based
-on its library calls. It tries to be an accurate re-creation and keeps
-the original bugs and lack of optimization.
+Finit's purpose is to build upon the general workings of fastinit and
+improve/optimize it for Xandros or alternative distributions running on
+the Eeepc. Finit comes in three flavors: finit is a replica of the Asus
+fastinit, finit-mod is an improved drop-in replacement for fastinit,
+and finit-alt is a generic replacement for other systems. Finit-mod
+and finit-alt were much improved with patches from Metalshark. 
 
-finit-mod.c is a fixed/improved version of finit.c.
-
-finit-alt.c is a fixed/improved version of finit.c for alternative Linux
-distributions running on the Eeepc (previously ffinit.c). Currently able
-to boot unmodified Mandriva Linux.
-
-See Makefile for configurable parameters to better suit your system.
+See more information at http://helllabs.org/finit/
 
 
-* Eeepc boot process
+Usage scenarios
+---------------
 
-The essential steps in the boot process carried out in initramfs are:
+1. Replace the original Eeepc 702 fastinit (finit-mod)
 
- ROOT=`sed 's!.*root=\([^ ]*\).*!\1!' < /proc/cmdline`
- mount -t proc proc /proc
- mount -t ext2 -o ro $ROOT /mnt-system
- mount -t ext3 -o rw /dev/sda2 /mnt-user
- mount -t unionfs -o dirs=/mnt-user=rw:/mnt-system=ro unionfs /mnt
- mount --move /mnt-system /mnt/mnt
- umount -l /mnt-user
- umount /proc
- exec switch_root /mnt /sbin/fastinit "$@" </mnt/dev/console >/mnt/dev/console
-
-If mounting the root filesystem fails, execute a maintenance shell. If
-mounting the user filesystem fails, fsck and reboot.
+2. Allow fast booting in alternative Linux distributions running on the
+   Eeepc and other netbooks (finit-alt)
 
 
-* Utilities available in the Eeepc initramfs busybox:
-
-[		cat		cp		cut		dd
-dmesg		echo		env		expr		false
-grep		insmod		ln		losetup		ls
-mdev		mkdir		mknod		mount		mv
-pivot_root	realpath	rm		rmmod		sed
-sh		sleep		switch_root	test		true
-umount		vi
+Finit-alt is distribution-specific. Currently it generates a finit-mdv
+executable for Mandriva 2008/2008.1 systems. Smurfy ported it to
+eeeXubuntu, and parts of his port have been merged to finit-alt.
 
 
-* Devices in the Eeepc initramfs /dev:
+Finit-alt features
+------------------
 
-console  fb  null  ram0  sda1  sda2  sda3  sr0  tty0
+Finit-alt reads configuration information from /etc/finit.conf. See
+the source code for available options.
 
 
+Rebooting and halting
+---------------------
 
-Using finit with alternative systems
-------------------------------------
+Finit handles SIGUSR1 and SIGUSR2 for reboot and halt, and listens to
+/dev/initctl so standard Linux reboot and halt commands should also
+work.
 
-Currently tested only with Mandriva 2008. Proceed with caution, there are
-problems related to udev and pam.
 
-1 - Add init=/sbin/finit-mdv to the kernel boot line
-
-2 - Provide a suitable /usr/sbin/services.sh, this is the one I use in my
-    test system:
-
-    mkdir /var/lock/subsys
-    chmod 1777 /var/lock/subsys
-    /etc/init.d/network start
-    dhclient eth0
-    /sbin/start_udev&
-    /etc/init.d/portmap start
-    /etc/init.d/nfs-common start
-
-3 - Provide /etc/hostname if you don't have it already
-
-4 - Set the pointer device in the X server configuration to /dev/input/mice
+Debugging
+---------
 
+Add finit_debug to the kernel parameter line to enable trace messages
+and to run a shell after the X server.

+    If you use KDE or need more services, see examples in contrib/
+
+3 - Create /etc/finit.conf with user, module, filesystems to check and
+    hostname parameters. See the included finit.conf for more information.
+    If no user is specified, user "user" will be used as default.
+
+4 - Set the pointer device in the X server configuration to /dev/input/mice

+Mandriva 2008.1
+---------------

+If you have a stuck nash-hotplug consuming 100% of CPU after the boot, you
