Edit the file "/etc/event.d/rcS-late"

seeks the following:

Code:

   sfdisk -l /dev/mmcblk0 | /bin/busybox awk \
        -v home_opts="$home_opts" -v fat_opts="$fat_opts" \
    -f /usr/lib/genfstab.awk > $tmp_fstab

add below:

Code:

   sfdisk -l /dev/mmcblk1 | /bin/busybox awk \
        -f /usr/lib/genfstab2.awk >> $tmp_fstab

should look like:

Code:

   fstab=/etc/fstab
    tmp_fstab=/tmp/fstab

    sfdisk -l /dev/mmcblk0 | /bin/busybox awk \
        -v home_opts="$home_opts" -v fat_opts="$fat_opts" \
    -f /usr/lib/genfstab.awk > $tmp_fstab

    sfdisk -l /dev/mmcblk1 | /bin/busybox awk \
        -f /usr/lib/genfstab2.awk >> $tmp_fstab

    cmp -s $tmp_fstab $fstab || cp $tmp_fstab $fstab
    rm -f $tmp_fstab

save changes and exit.

Now copy the file genfstab.awk:

Code:

cp /usr/lib/genfstab.awk / usr/lib/lib/genfstab2.awk

Edit "/usr/lib/genfstab2.awk" and leave it like this:

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
}

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

the rest delete it.

Now you can restart, each time you start to check that the microSD has a swap partition and if so will mount.

I'm seeing a more elegant and does not need extra partition or cards.

The manipulation of system files can leave the N900 unusable.
I take responsibility for the results.
I really worked.
