N900 Install

Mer Image

The latest release as of this post is 0.17testing4. 

# you need an ext3 formated MicroSD card.
mount -o noatime /dev/mmcblk1p1 /media/mmc1/

# go hence
cd /media/mmc1/

wget http://stskeeps.subnetmask.net/mer/0.17testing4/mer-armel-generic-image-v0.17testing4.tar.gz

# Untar it verbally to see the majick.
# Note this will create dirs like ./usr and ./lib etc, so you don't want stuff pre-existing in those dirs.
tar zxvf mer-armel-generic-image-v0.17testing4.tar.gz

# sync and live free!
sync

bootmenu

You need to have getbootstate version 1.0.35+0m5 or greater for this to work. 

dpkg -l getbootstate

(As a side note, getbootstate is close software. Please vote for this bug and/or clamour for it to be released as free software.) 

# Grab this package:
wget http://www.daimi.au.dk/~cvm/bootmenu_1.6_armel.deb

# Be root
sudo gainroot

# Install bootmenu
dpkg -i bootmenu_1.6_armel.deb

Then tappy tap tap the bootmenu install icon and answer yes.

Now you need to set up Mer in the menu for bootmenu. See also: Mer bootmenu docs.

I put everything on the first and only partition on an ext3 formatted "external" MicroSD card (the one that's right next to the camera). 

# edit/create this file to create a boot menu item for Mer:
vim /etc/bootmenu.d/mer.ext.item

# Make it look justa lika thisa:

ITEM_NAME="Mer (external SD, partition 1)"
ITEM_ID="mer"
ITEM_DEVICE="${INT_CARD}p1"
ITEM_MODULES="mbcache jbd ext3"
ITEM_FSTYPE="ext3"
ITEM_FSOPTIONS="noatime,ro"
