info about some of the packages I've uploaded to extras-devel

== [http://maemo.org/packages/view/debhelper7/ debhelper7] ==

see also http://wiki.maemo.org/Packaging

A backport of Debhelper 7 for Fremantle is available in extras-devel.
It works transparently and can coexist with debhelper 5 in the SDK.
It also works on the autobuilder, if you specify
 Build-Depends: debhelper7
in debian/control.
The following lines in debian/rules are necessary to use it:

PATH:=/usr/bin/dh7:/usr/bin:$(PATH)
 export PATH
 SBOX_REDIRECT_IGNORE=/usr/bin/perl
 export SBOX_REDIRECT_IGNORE

We are working on enhancement to make optification is easier, i.e. direct installation of files in the /opt hierarchy.

If you also need a more recent cdbs, then use the package [http://maemo.org/packages/view/cdbs-dh7/ cdbs-dh7],
which conflicts with the standard cdbs and does not work on autobuilder yet.

To replace several tools in scratchbox you can also use the following line as a template
 SBOX_REDIRECT_IGNORE:=$(shell echo /usr/bin/{perl,dh_*} | sed "s/ /:/g")

== [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.

== full [http://wiki.maemo.org/Opt_Problem optification] ==

Ideally addon software should be installed only in /opt without any symlinks in / (NAND)
in accordance with [http://www.pathname.com/fhs/2.2/fhs-3.12.html FHS].
/usr/local should be moved and symlinked to /opt/local and is reserved for own programs not maintained by dpkg.

A package may either install its files directly (for small packages) in the /opt/maemo hierarchy (bin,etc,lib,man,share)
or in a separate directory /opt/<package> with its own hierarchy (bin,etc,lib,man,share).
For the latter solution packages should symlink all non-private files to /opt/maemo/{bin,etc,lib,man,share}
and the search paths of Maemo need to be adjusted in /etc/profile and  /etc/osso-af-init/af-defines.sh:

* PATH=$PATH:/opt/maemo/usr/bin  (and sbin for root)
* ld.so.conf: add /opt/maemo/usr/lib
* locales: [https://bugs.maemo.org/show_bug.cgi?id=8363 LOCPATH]=LOCPATH=/usr/share/locale:/opt/maemo/usr/share/locale
* MANPATH=/opt/maemo/usr/share/man
* pkgconfig: /usr/share/pkgconfig:/opt/maemo/usr/share/pkgconfig
* info in info?: /usr/share/info:/opt/maemo/usr/share/info
* apps in hildon ?: /usr/share/applications:/opt/maemo/usr/share/applications
* icons in hildon ?: /usr/share/icons:/opt/maemo/usr/share/icons
this list may be incomplete - please help to complete it

As NAND is much faster than eMMC a cache manager could mantain a list
of very often used binaries and libraries in /opt and automatically
copy them and symlink them to a fixed size cache in NAND.

TMPDIR=/var/tmp should be moved to /opt/tmp
or /var/opt should symlink to /opt/var and contain a larger tmp directory.
== chroot instead of /opt ==

== Safely free some space on rootfs ==

This script shows you how much space is freed and it
also detects whether something has already been moved.

# install gainroot
# copy & paste the following script to /tmp/moreroot.sh (or upload it via SSH or copy it from MyDocs)
# in Terminal run
 sudo sh /tmp/moreroot.sh

The script:
 
 #!/bin/sh
 # N900 script to safely free space on rootfs
 # © 2010 by Thomas Tanner <tanner@maemory.com>
 # licensed under GPLv3
 
 # move root stuff to /home
 dirs="usr/share/icons usr/share/nokia-maps usr/share/themes usr/share/fonts usr/share/locale usr/lib/locale var/lib/apt"
 #optional: var/lib/dpkg
 if test -d /home/var/cache/apt; then
   # keep existing apt cache
   rm -rf /var/cache/apt
   ln -s /home/var/cache/apt /var/cache/apt
 else
   dirs="$dirs var/cache/apt"
 fi
 (cd / && du -sc $dirs)
 for d in $dirs; do
     test -L /$d && continue
     echo moving /$d
     rm -rf /home/$d
     mkdir -p /home/$d
     cp -a /$d /home/$d/..
     rm -rf /$d
     ln -s /home/$d /$d
 done

== Reflashing & Restore ==

this is a slightly modified version of the script I use to restore my N900 after a reflash.
My reflashing procedure is:

# store all settings with Backup on my SD card
# reflash with standard http://wiki.maemo.org/Updating_the_firmware, i.e.
 sudo flasher-3.5 -F RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin -f -R
# restore old backup except programs
# install gainroot
# in Terminal:
 sudo sh /home/backup/restore
with following script in /home/backup (feedback and patches are welcome).
It expects that you made a backup of /root and your selected modified files (e.g. /etc/ssh) in /home/backup.
The file "pkgs" should contain a list (line by line) of the package names you want to install.

#!/bin/sh
 # N900 restore script
 # © 2010 by Thomas Tanner <tanner@maemory.com>
 # licensed under GPLv3
 
 set -x
 # script and data must be in /home/backup
 cd /home/backup
 # remove old opt
 rm -rf /home/opt
 mkdir /home/opt
 # copy /root backup
 rm -rf /root
 cp -a root /
 # copy modifed files for /etc
 cp -a etc/* /etc
 
 # enable user ssh login with ~/.ssh/authorized_keys
 sed 's/^user:!/user:\*/' /etc/passwd > /etc/passwd.tmp
 cp /etc/passwd.tmp /etc/passwd # mv
 
 # move root stuff to /home
 dirs="usr/share/icons usr/share/nokia-maps usr/share/themes usr/share/fonts usr/share/locale usr/lib/locale var/lib/apt"
 #optional: var/lib/dpkg
 if test -d /home/var/cache/apt; then
   # keep existing apt cache
   rm -rf /var/cache/apt
   ln -s /home/var/cache/apt /var/cache/apt
 else
   dirs="$dirs var/cache/apt"
 fi
 (cd / && du -sc $dirs)
 for d in $dirs; do
     test -L /$d && continue
     echo moving /$d
     rm -rf /home/$d
     mkdir -p /home/$d
     cp -a /$d /home/$d/..
     rm -rf /$d
     ln -s /home/$d /$d
 done
 
 mount /home/user/MyDocs # non-standard partition layout
 apt-get update
 apt-get -y install mc python-support openssh-server
 
 # install my standard set of packages
 apt-get -y install `cat pkgs`
