sfdisk --force /dev/mmcblk0 < sf
mkfs.ext3 /dev/mmcblk0p1

After this need make normal fstab. I am not sure is it used (fstab) some where on n900 or not but I prefer to have it clear...
You can modify /etc/event.d/rcS-late or /usr/lib/genfstab.awk.
I modified /usr/lib/genfstab.awk.
here my file:

Code:

#!/usr/bin/awk

BEGIN {
	# states so that we don't end up having more than one
	# of home or MyDocs; we can have as many swaps as we find
	__home = 0
	__fat = 0

	print "# autogenerated"
	print "rootfs / rootfs defaults,errors=remount-ro,noatime 0 0"
}

/^\/dev\/mmc/ { start=1 }
start == 1 && $6 == 82 {
	printf "%s none swap sw 0 0\n", $1
}

start == 1 && $6 == 83 && !__home {
	printf "%s /home ext3 %s 0 0\n", "/dev/mmcblk0p2", home_opts
	__home++
}

start == 1 && $6 == 83 && !__fat {
	printf "%s /home/user/MyDocs ext3 %s 0 0\n", "/dev/mmcblk0p1", home_opts
	__fat++
}

For mounting it and make it work need make some small fix in ke-recv. First file probably more simple to just rewrite. This is "/usr/sbin/mmc-mount". I tried to make more universal. It could work now with ext3 and vfat. In case vfat it is require 3 (original amount of parameters) or 4 arguments.

Code:

#!/bin/sh
# $1 - device
# $2 - mount point
# $3 - rw or ro mode for mounting
# $4 - file system vfat or ext3. If it is absent mount vfat.


. /etc/default/mount-opts #load standard parameters for mounting FAT and ext3
#home_opts="rw,noatime,errors=continue,commit=1,data=writeback"
#fat_opts="noauto,nodev,noexec,nosuid,noatime,nodiratime,utf8,uid=29999,shortname=mixed,dmask=000,fmask=0133,rodir"

case "$4" in	
	ext3)
		SYS=ext3
		PAR=$home_opts
	;;
	*)
		SYS=vfat
		PAR="$3,$fat_opts"
	;;
esac

COMMAND="mount -t $SYS -o $PAR "$1" "$2" > /dev/null"
#echo $COMMAND
eval $COMMAND
#mount -t vfat -o $3,noauto,nodev,noexec,nosuid,noatime,nodiratime,utf8,uid=29999,shortname=mixed,dmask=000,fmask=0133,rodir "$1" "$2" > /dev/null

Second file which need to change is "/usr/sbin/osso-mmc-mount.sh"
Differences is here:

After this modification I have 2gb mounted /home (ext3) and 27gb on /home/user/MyDocs (ext3). Camera is working. When I connect device to computer (linux) /home/user/MyDocs unmounted (on n900) and exposed to notebook. For have possibility edit files on 27Gb partition on computer (linux, ubuntu) need execute (only once):

Code:

sudo addgroup --gid 29999 n900
sudo adduser YourUserName n900

After this you will be able to edit files on device. When you will disconnect device this partition will be remounted on" /home/user/MyDocs". Originally I had problem with files created on notebook. All this files had User and group from user and group on notebook. Now after mounting this partition back to n900 group and owner will be automatically changed to user:users (from n900).

EDIT: modified file "/usr/sbin/osso-mmc-mount.sh" (I didn't change now differences). In new file improved permissions changes for files. It is more comfortable for using with other linux computer. Before last modification some files was read only on computer because my script provide access to files by group (user on n900 and computer different). Now all files will have permissions: rwXrwXnnn (n-don't changed).
