== CLI icon ==
 
-
 
-
For your convenience I have uuencoded Tim Samoff's [http://lists.maemo.org/pipermail/maemo-community/2010-January/003870.html CLI icon]
 
-
which is supposed to be added to the debian/control file of CLI apps. You can download it [http://n900.tannerlab.com/tools/cli.icon.txt here].

== [http://maemo.org/packages/view/kernel-flasher-maemo/ custom Linux kernel] ==
 
-
 
-
My custom kernel which contains probably everything one could need on the N900:
 
-
 
-
This custom kernel contains additional modules for IPv6, packet filtering,
 
-
NAT, tunneling, kernel configuration, Wifi mesh networking,
 
-
ext4, XFS, reiserfs, NTFS reading, NILFS2, ISO9660, UDF, CIFS, automounter,
 
-
UNIONFS, device mapper and dmloop, cryptography, cryptoloop,
 
-
EFI partitions, UTF8 codepages, mouse+joystick input,
 
-
USB/IP and generic USB device drivers.
 
-
It shows a boot logo.
 
-
 
-
Just install the package "kernel-flasher-maemo" from extras-devel/non-free (section System) and reboot.
 
-
Reverting to the original kernel is simple:  "apt-get install --reinstall kernel kernel-flasher"  or reflash only the original kernel image.
 
-
see [http://talk.maemo.org/showthread.php?t=43420 TMO page] for more details.

== GNU tools ==
 
-
the crippled busybox is installed on the N900.
 
-
command line users prefer the real GNU tools.
 
-
these are the optified packages for the device.
 
-
Most of them do not take use more RAM than busybox (a few KBs)!

A package for Maemo (tested on N800) that allows a package to set environment variables like XDG_DATA_DIRS is available: [http://svn.nomike.org/playground/trunk/opt-support/ opt-support]. I propose packages depend on opt-support and in their postinst add their variables to the file "/etc/profile.env". -- dannym

== Safely free some space on rootfs ==
+
-
 
+
-
[http://n900.tannerlab.com/tools/moveroot.sh This script] shows you how much space is freed.
+
-
It can also detect whether some directories have already been moved.
+
-
WARNING: Although this script works for most users, you should always perform a backup before running it.
+
-
Do not use this script if you have already used some other methods or scripts from [[Free_up_rootfs_space]]!
+
-
In this case reflashing is recommended.
+
-
 
+
-
# install the rootsh package from extras
+
-
# download the [http://n900.tannerlab.com/tools/moveroot.sh script] to your MyDocs (or upload it via SSH)
+
-
# in Terminal run
+
-
sudo gainroot
+
-
sh /home/user/MyDocs/moveroot.sh
+
-
 
+
-
It should have freed about 95MB on your rootfs.
+
-
Upgrading the firmware OTA after using the script is supposed to work.
+
-
If you reflash the firmware the script will automatically remove the files from the old firmware
+
-
when you run it again.
+
-
 
+
-
[http://n900.tannerlab.com/tools/unmoveroot.sh This untested script] reverts the modifications and moves as many as possible files back to rootfs.
+
-
Make sure that you have enough space on rootfs for that. Otherwise it will abort the operation. Instructions are the same as for moveroot.sh,
+
-
except that you call unmoveroot.sh.

== On-device flashing of a custom kernel image ==

# you have a kernel image /path/zImage (with it's modules installed)
+
-
# install the package "sdk-fiasco-gen" from SDK
+
-
# become root: "sudo gainroot"
+
-
# make a "fiasco" :)
+
-
fiasco-gen -o /path/zImage.fiasco -g -k /path/zImage
+
-
# flash it
+
-
/sbin/fiasco-image-update /path/zImage.fiasco
