+1.0 2013-03-23
+==============
+-Using buildroot now to create the rootfs.
+-updated userspace tools(e. g. busybox).
+-glibc replaced with uclibc and everything recompiled against uclibc
+-/rescueOS/usb-mass-storage-enable.sh: Work if sd card is inserted or not(known mmcblkX number issue on N900)
+-shipping wifi firmware
+-corrected dhcp business with /etc/resolv.conf
+-decreased size of the initrd
+
+====
+
+0.5.4 2013-01-05 
+Nothing special but useful changes:
+-midnight commander removed as it was eating too much space and I doubt people were actually using it.
+-Now after bootup, the system asks the user whether he wants to enable anonymous ftp up and downloads everywhere.
+Then whether telnetd should be started and finally asks whether usb networking should be enabled.
+=================================
+0.5.3
+Short note: it disappeared from the server (some problems with my hoster).
+Development is pretty much stalled. I am focusing on other things.
+Contributions otoh are still welcome.
+
+
+-Including Pali's script which should fix some messed up maemo /dev/ device nodes (iirc, this can happen with uboot fun)
+
+
+0.5 2012-03-03, version 0.5.2
+Boring and nothing exciting:
+* tar is now gnu tar, not busybox's version for convenience
+* /tmp/ for some reason never existed, now it does :S
+* Mountpoints /mnt/free1, /mnt/free2, /mnt/free3 (how noteworthy!) 
+* PS1 was set to show the current directory you are in.
+
+
+0.5 2012-01-22, version 0.5.1
+* Battery capacity watchdog tells user at 45 % capacity to charge the 
+  battery. Type "stfu" if the messages annoy you.
+
+0.5 2011-11-02, version 0.5
+* Updated busybox to 1.19.3
+* User can append autostart=/path... option in the kernel 
+* command line to run a script right after bootup. 
+* tcpsvd included for ftpd. For example, "tcpsvd -v 0.0.0.0 21 
+  ftpd -w" enables anonymous down- and uploads everywhere. 
+* By Request: Midnight Commander 4.8 included. As functions 
+  keys are not available/mapped, use ESC+number. Still borked. 
+* cleaner shutdown.
+
+
+0.4 2011-09-02:
+* e2fsprogs
+* dosfstools
+* Now also available as an initrd image.
+
+
+0.3 2011-08-26:
+* Battery charging support. (via ShadowJK's h
+  http://enivax.net/jk/n900/">meegocharge script</a>)
+
+0.2 2011-08-21:
+* Decreased rootfs size by a factor of 10
+* First poor-man script to create an archive of the maemo rootfs.¹)
+* Takes the WiFi-Firmwares on first boot from maemo root if wished by 
+  the user.¹
+* Bug which caused the wlan interface number to increase on every reboot 
+  fixed. 
+* bash and job control
+* Typo in /rescueOS/umount-maemo-root.sh fixed 
+
+0.1 2011-07-31:
+* First release 
+* WiFi Support
+* ubifs mounting support (maemo root for example)

+Documentation of RescueOS
+=========================
+RescueOS is a rescue solution for the Nokia N900, distributed
+as an initrd image. It has several features, most
+notable:
+
+mounting maemo /
+EMMC access(can mount maemo home and MyDocs partition)
+WiFi support
+USB mass-storage mode
+USB networking
+Battery charging
+
+Users must be familiar with the Linux console.
+
+This project is _NOT_ the meego rescue initrd.
+
+
+Update: I don't provide a tarball anymore. 
+
+How does it work?
+~~~~~~~~~~~~~~~~~
+The flasher utility loads rescueOS. This makes it unnecessary 
+to modify the bootloader or maemo's /sbin/preinit. 
+
+By using the "-l" option, we do not flash the kernel or initrd image.
+It only loads the kernel into RAM. No modification on
+the NAND or bootloader happens.
+
+
+
+Usecases
+~~~~~~~~
+In fact, most users do not need it. Either way, possible usecases:
+
+-Changing typos in bootscripts which prevent an operation system
+(e.g. maemo) to boot.
+
+-Backuping files prior to a reflash.
+
+-Charging the battery (when maemo is dead).
+
+-Modification of the EMMC partitions and partition table.
+
+-Backup & Restoring maemo rootfs.
+
+-fsck file system checks
+
+-and more...
+
+Booting the initrd
+~~~~~~~~~~~~~~~
+You can not store persistent data, e.g. WiFi firmwares from maemo 
+as everything happens in RAM. 
+
+flasher-3.5 -k 2.6.37 -n initrd.img -l -b"rootdelay root=/dev/ram0
+
+wait for "suitable device not found..." and connect the N900 to your 
+Linux box through USB.
+
+
+~~~~~~~~~~~~~~~
+How to use it
+~~~~~~~~~~~~~~~
+It boots and you get a bash shell.
+
+The folder /rescueOS/ contains some scripts for various tasks. Not all of them 
+are completed yet. They help you with the usual stuff, e.g. mass-storage
+mode, maemo root mounting, usbnetworking, WiFi setup etc.
+
+Mounting maemo root
+-------------------
+/rescueOS/mount-maemo-root.sh
+This scripts mounts the maemo root to /mnt/maemo. 
+
+/rescueOS/umount-maemo-root.sh
+
+USB Networking
+-------------
+/rescueOS/usbnetworking-enable.sh
+Sets up USB networking in the following way:
+ifconfig usb0 192.168.2.15 up
+ifconfig usb0 netmask 255.255.255.0
+route add 192.168.2.14 usb0
+
+To disable it: /rescueOS/usbnetworking-disable.sh
+
+USB Mass-Storage mode
+--------------------
+/rescueOS/mass-storage-enable.sh
+Makes /dev/mmcblk1p1 and /dev/mmcblk1p2 available for the mass-storage
+mode. These are the EMMC home partition and MyDocs in maemo.  
+
+/rescueOS/mass-storage-disable.sh: Deactivates mass-storage mode.
+
+
+WiFi support
+------------
+It has wpa_supplicant, but without EAP support. This should be ok for
+most home networks which use a PSK.
+
+Give the following a try:
+
+wpa_passphrase [essid] [password] > /wlan.conf
+sh /rescueOS/setup-wpa-wifi.sh
+
+For DHCP, use udhcpc -i wlan0.
+
+You need the firmware files of course: /rescueOS/firmware-from-maemo.sh
+
+Battery charging
+----------------
+By using ShadowJK's charge21 script. Use it only with the wallcharger,
+as it pulls 950 mA, and USB is not designed for that 
+(some ports can do it though, don't try if in doubt.)
+ 
+/rescueOS/charge21.bash
+
+Shutdown
+--------
+poweroff 
+
+Root password
+-------------
+rootme
+
+
+Contributions and suggestions are welcome. Write to me (NIN101 on freenode).
