:*''[[wikipedia:dm-crypt|cryptsetup]]'' is only needed for the option to provide password protection and encryption for the persistent /home/liveuser folder. It is not necessary if one applies the recommended {{Code|--unencrypted-home}} option. The {{Code|--unencrypted-home}} option is preferred because the reduced overhead improves robustness with the compressed ''[[wikipedia:SquashFS|SquashFS]]'' file system employed by the Live USB deployment.

:: The ''livecd-iso-to-disk'' installation method has advantages over the ''liveusb-creator'' method by allowing the creation of a separate, persistent /home/liveuser folder with the <tt>--home-size-mb ''NNN''</tt> option. This feature avoids consumption of the write-once persistent overlay for Activity storage (see [[LiveOS image]]) and allows one to update the OS image while keeping the user files (by running the script against your existing installation but <u>leaving out</u> the --home-size-mb NNN option).
** {{Highlight|'''Note''': Subsequent USB or SD devices may be installed from a running Sugar on a Stick image that was installed with the livecd-iso-to-disk script downloaded after 15 February 2011 (but not those installed by other methods) by running this command from a root user Terminal window:}}

::* The {{Code|--delete-home}} option is used to avoid an error message while requesting both a new home (with {{Code|--home-size-mb}}) and a persistent home (indirectly with {{Code|--unencrypted-home}}). You wouldn't use the --delete-home option on an upgrade of the operation system only.

:Depending on the size of your USB stick, you may have to decrease {{Code|--overlay-size-mb}} and {{Code|--home-size-mb}} values (for example, for a 1-GB stick, use 300 for the overlay and 175 for the home folder).
