I like but I see a limitation because you say what the swap.
I watch as it automatically adapt to the example that I put myself and not depend on the human well.
How to place her at the start to run?

Here's a startup script I made (goes in /etc/events.d/) based on elipsoid's script to check for the microSD swap file before changing the swap configuration. I broke some of the commands into two lines because depending on how you partitioned your MicroSD, you might get un-suppressable warning messages from sfdisk that would mess up the process.

Code:
start on started hildon-desktop
stop on starting shutdown
console none
service
script
drivelist=$(sfdisk -lnq /dev/mmcblk1)
swapmicro=$(echo "$drivelist" -n | grep swap | awk '/mmcblk1p2/ {print $1}')
if [ "$swapmicro" ]; then
swapon $swapmicro
swapoff /dev/mmcblk0p3
swapon /dev/mmcblk0p3
fi
end script

With the code as you wrote it I do not ever ride swap the SD.
I would remove the following line:
Modify the line ...
For these other ...
Show only that partition is a swap rate, regardless of the number of partition.
Then modify the following lines ...
For these, that would trigger the swap of the card as your indicastes:

I would remove the following line:
Code:
testmicro = "/ dev/mmcblk1p2"
Code:
swapmicro = $ (echo "$ drivelist"-n | grep / dev/mmcblk1p2 | awk '/ mmcblk1p2 / {print $ 1}')
Code:
drivelist = $ (sfdisk -ln /dev/mmcblk1 | grep swap)
swapmicro = $ (echo "$ drivelist"-n | awk ' /mmcblk1p/ {print $ 1}')
Then modify the following lines ...
Code:
if [ "$ testmicro" == "$ swapmicro" ]; then
swapon / dev/mmcblk1p2
swapoff / dev/mmcblk0p3
swapon / dev/mmcblk0p3
Code:
if [ $ swapmicro ]; then
swapon $ swapmicro
swapoff /dev/mmcblk0p3
swapon /dev/mmcblk0p3

My script worked fine but I'm going to incorporate your improvements into my earlier post (with one little change to deal with sfdisk's warning messages)

I look forward to this script! Good idea.
.. If I can help, I will love it.

Good stuff guys, this is looking very polished and robust - certanly a smarter way of doing things and nice and compact.
Gameboy, the -q switch for sfdisk surpresses warning messages, I've just tried it and it works.

I tested with the amendment proposed and returns nothing if there are error messages by sfdisk.
I confirm that the "-q" sfdisk output prevents error messages.

As I am personally going to stick to running a script manually after a reboot, and following Whitewolfs lead using sfdisk, I have added the lines below to my tuning script to ensure the uSD swap is available before making any changes.
testmicro="/dev/mmcblk1p2" swapmicro=$(sfdisk -l /dev/mmcblk1 | grep /dev/mmcblk1p2 | awk '/mmcblk1p2/ {print $1}') if [ "$testmicro" == "$swapmicro" ]; then swapon /dev/mmcblk1p2 swapoff /dev/mmcblk0p3 swapon /dev/mmcblk0p3 else echo "Cannot find swap parition on uSD card, swap still on internal memory" fiI have tested this by running with no SD card, and it works; if mmcblk1p2 is not present it will make no swap changes.
I'd like to be able to get this added to the wiki page, as the current instructions only sets up the faster swap as secondary- and it will never get used considering the huge default primary swap. As I've said I'm kinda new to all this so I wouldn't dream of doing so unless somebody with some experience had a look at the above code and gave me some feedback.
Does it look safe enough to add to the wiki?
