[SoaS] Optimizing the preparation of an operational SoaS USB key

Hello,

Many people want to prepare operational SoaS USB keys.

Could you verify the protocol
"PREPARATION OF AN OPERATIONAL SoaS USB KEY"
attached at the end of this message ?

All comments are welcome !

NB: Part of this protocol could be added on
http://wiki.sugarlabs.org/go/Sugar_on_a_Stick/Blueberry#Download_locations

One of the main feature of Sugar is its Journal.
This Journal is rapidly saturated on USB keys.

Question 1 : Is it possible to increase its size ?

Its standard size seems to be 425 MB,
for persistent storages equal to
2012 MB, 3017 MB or 3213 MB (on 4 GB sticks) or
4095 MB (the maximum size imposed on a 16 GB stick).

Question 2 : Is it possible to display a warning
message at the top of the Journal when the available
storage size is less then 50 M (for example) ?

Question 3 : Activities seem to be updated
through the Journal. This may use up to 85 MB !
Is it possible to recover this place without
suppressing the updated Activities ?

Question 4 : Large files (e.g. ogg, pdf, ...) can be
easily imported from other USB keys by specific Activities
(like Browse ...). But the Journal is rapidly overcrowded !
Is it possible to store these files as classical
files, link them to the proper Activity,
and liberate the Journal.

NB: Files may also be imported with the Terminal
but this is not very convenient for new users !

All information on Journal optimization is welcome !

Thank you,

================================================================
PREPARATION OF AN OPERATIONAL SoaS USB KEY
With SoaS-2-Blueberry (version 0.86.3)
================================================================

Choose a 4 GB USB Key
(presently larger keys are not completely used).

Keys with a led flashing during data transfers are recommended
for safety reasons.


A. CREATION OF A LIVE SoaS USB KEY

Follow instructions on
http://wiki.sugarlabs.org/go/Sugar_on_a_Stick/Blueberry#Download_locations

All available space should be dedicated to "Persistent Storage".

Creation of a live USB key needs approximately 10 min,
depending on the USB transfer rate and on the size
of the persistent storage.


B. BOOT ON THE NEW SoaS USB KEY

- Shut down your computer.

- Insert the SoaS USB key.

- Start your computer. You may have to immediately press
   a key ("Esc", "F10", ...)  for booting on the SoaS USB key.
   In other cases you may have to boot with an auxiliary CD.
   See "Boot Helper" on
http://wiki.sugarlabs.org/go/Sugar_on_a_Stick/Blueberry#Download_locations


C. CHECK ON JOURNAL CAPACITY

- On the first boot, choose the proper user icon.

- Push the cursor on the "Journal" icon just below the user icon
   on the activity screen.

The Journal capacity is displayed :
usually around 425 MB at the first boot.


D. LOCALIZATION

- Push the cursor on the user icon on the activity screen.
- Push the cursor on the user name
- Click on "My Settings"
- Click on "Keyboard"
- Choose the proper "Keyboard Layout(s)"

2 Arabic [azerty, Arabic]
3 Berber languages [Tifinagh, Morocco]

Key(s) to change layout : Alt-Shift

NB: These choices could be optimized by specialists.

- Click on the upper right "Check" sign.

- Click on "Language".

Choose the proper language(s) depending on your country.

- Click on the upper right "X" sign.

NB 1: After localization, there is nearly no change
in the Journal capacity

NB 2: Keyboard(s) and language(s) can be checked later on with the Speak 
activity.

with a 100 MB/s connexion
(update time in February 2010 for 18 updates corresponding to 61 MB).

NB: After update, there is a large decrease
in the Journal capacity :
425 MB -> 340 MB, for example.
