The starting point is a PC, and a clean 2GB or 4GB USB stick to use as the target device.

It does not really matter what operating system you are using. To make your persistent Sugar on a Stick you will [[Sugar on a Stick/Boot|boot your computer]] with a Sugar LiveOS "host" media, which might be:

* A CD-ROM made from the Sugar.iso available from [[Sugar on a Stick/Downloads]]
:The CD-ROM could be made from the default CD writing software of your PC.
* A UNetbootin USB as described in [[Sugar on a Stick/Installation Process]]
* A USB stick written with the Linux command {{Code|dd}} from the Sugar.iso available from [[Sugar on a Stick/Downloads]],
sudo dd if=Fedora-Live-SoaS''version''.iso of=/dev/sdX bs=8M
* A USB stick written with Nautilus (Files).
* or any other Sugar on a Stick.

== Method ==

Boot your computer with the chosen LiveOS media. Once Sugar is running,

''''Either''' enter a console with Ctrl+Alt+F2,

'''or''' open the Terminal Activity, [[File:Activity-terminal.png|bottom|link=http://en.flossmanuals.net/terminal]], from the <span class=plainlinks>[http://wiki.sugarlabs.org/images/9/9b/Home_ListView_button.png Home list View]</span>.

Plug a clean 2GB memory stick, the target device, into the PC.

Run the command,
df -Th
to establish the device location.
{{Show|extra detail.
|<pre>
On the first pass, before plugging in the target stick, expect output like this:

[root@localhost ~]# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/mapper/live-rw ext4 2.9G 2.1G 773M 74% /
devtmpfs devtmpfs 2.0G 0 2.0G 0% /dev
tmpfs tmpfs 2.0G 72K 2.0G 1% /dev/shm
tmpfs tmpfs 2.0G 632K 2.0G 1% /run
tmpfs tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup
/dev/sr0 iso9660 670M 670M 0 100% /run/initramfs/live
tmpfs tmpfs 2.0G 32K 2.0G 1% /tmp
varcacheyum tmpfs 2.0G 0 2.0G 0% /var/cache/yum
vartmp tmpfs 2.0G 0 2.0G 0% /var/tmp

After the target stick is inserted, the command produces an extra line at the bottom:

[root@localhost ~]# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/mapper/live-rw ext4 2.9G 2.1G 773M 74% /
devtmpfs devtmpfs 2.0G 0 2.0G 0% /dev
tmpfs tmpfs 2.0G 72K 2.0G 1% /dev/shm
tmpfs tmpfs 2.0G 632K 2.0G 1% /run
tmpfs tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup
/dev/sr0 iso9660 670M 670M 0 100% /run/initramfs/live
tmpfs tmpfs 2.0G 32K 2.0G 1% /tmp
varcacheyum tmpfs 2.0G 0 2.0G 0% /var/cache/yum
vartmp tmpfs 2.0G 0 2.0G 0% /var/tmp
/dev/sdb1 vfat 1.8G 2.0K 1.8G 1% /run/media/liveuser/SanDisk

The new line reads:
/dev/sdb1 vfat 1.8G 2.0K 1.8G 1% /run/media/liveuser/SanDisk
and the first element reports that the target device is represented as /dev/sdb1.
Write down your target in the format, /dev/sd?1, where ? is likely to be b, c, d or e.
</pre>}}

Unmount the target USB stick - edit to reflect your target:

umount /dev/sd?1

For a nominal 2GB stick, enter this command - edit to reflect your target:

su -c "livecd-iso-to-disk --reset-mbr --overlay-size-mb 500 --home-size-mb 800 --unencrypted-home /run/initramfs/livedev /dev/sd?1"

Writing the stick will take some time, and when successful will finish by reporting

"Target device is now set up with a Live image!"

Your persistent Sugar on a Stick is ready to run.

Shut down your "host" Sugar LiveOS media system [[Sugar on a Stick/Boot|and boot the new.]]

For a nominal 4GB stick use this command,

su -c "livecd-iso-to-disk --reset-mbr --overlay-size-mb 1000 --home-size-mb 1600 --unencrypted-home /run/initramfs/livedev /dev/sd?1"

== Maintenance ==

The persistent overlay status may be queried by issuing this command on the live system:
dmsetup status live-rw
The returned value may look like this:
live-rw: 0 8388608 snapshot 42296/204800 176
where the fraction after 'snapshot' for the logical volume is that of 512-byte sectors consumed in the overlay.
