<div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace">I've attached several patches to the bugzilla ticket, which breakdown the changes for somewhat easier review:</font></div>
<div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace">1. One each, for the new --copy-overlay and --copy-home options and</font></div>
<div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace"> update to livecd-iso-to-disk.pod for help on usage.</font></div><div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace">2. Another pair for the --builder-message <message> and </font></div>
<div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace"> --releasefile <filepath> options with .pod changes for help.</font></div><div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace">3. And finally a pair that addresses the new to have usage help within</font></div>
<div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace"> the livecd-iso-to-disk shell script.</font></div><div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace"><br>
</font></div><div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace">The --copy-overlay and --copy-home additions extend the utility of the script to allow the user/learner to replicate their personally modified image.</font></div>
<div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace">The --builder-message and --releasefile options label the remixed image to prevent confusion with the pristine versions, and to credit the builder for their changes.</font></div>
<div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace">Because the livecd-iso-to-disk script is so often redistributed in standalone fashion, it is worth the space and effort to include usage documentation and help in the script itself. This should help the general understanding of the script and its methods, given its presently-limited documentation.</font></div>
<div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace">In the 1st and 3rd patches, there are many white-space changes that I couldn't avoid in order to clarify the local variable name changes made to match the broader scope of the script (for example, $ISO to $SRC and $USBDEV to $TGTDEV). In addition, there are some block order changes that make use and documentation easier to follow.</font></div>
<div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace">I also standardized the Bash conditional expression and list pipeline style to the more modern, [[ Expression ]] && [[ Expression ]] format. (See </font><font class="Apple-style-span" face="'courier new', monospace"><a href="http://wiki.bash-hackers.org/syntax/ccmd/conditional_expression">http://wiki.bash-hackers.org/syntax/ccmd/conditional_expression</a>.)</font></div>
<div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace">This means that variables within the special double brackets need not be quoted and the old test-type operators -a -o should not be used.</font></div>

<div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><div class="gmail_quote"><font class="Apple-style-span" face="'courier new', monospace">SoaS deployments in schools may want to configure images without any operating system overlay (providing consistency and stability) and use the extra, persistent storage space for recoverable home directory storage that can be easily backed up, shared, or swapped (by remounting the /home folder).
