Boy, was I barking up the wrong tree in the last message.<br>Think I've found the right tree this time. :-) <br><br>See:<br><br> <a href="http://www.linux-live.org/">http://www.linux-live.org/</a><br><br>Needs some embellishments for our purposes.
<br><br>Let's recap the scenario. <br><br>Assume we are out making a presentation, <br><br>introducing OLPC to folks who have maybe read <br>some articles about it, maybe not. <br><br>We arehoping to recruit them as developers.
<br><br>We have an hour or so. <br><br>For some hands on experience<br>
We
have asked them to bring <br> their laptops, <br> and a usb flash drive<br><br>We don't have time for any complicated installation, and they have<br>a random assortment of hardware, and operating systems. <br>
<br>Most of them have environments that are difficult, if not nearly
<br>impossible to work with. <br><br>In case they don't have enough free disk<br>
space, or there is some other problem installing<br>an image on their hard drive<br><br>we bring a plain vanilla sever with a <br>open shared network readonly filesystem.<br><br>In case of difficulty with their usb drive, or if
<br>they just forgot it. <br><br>We have available<br>1 GB usb flash $20-$30 from a reputable source<br>they can borrow or purchase.<br>
<br>We give them LiveCd/Dvd <br> / is a unionfs of<br> rw filesystem on usbdrive <br> ro Mike's image ported to FC6, or<br> just about any OS image for that matter<br> but we don't care about that.
<br><br>Mikes image might fit on compressed LiveDvd<br>but won't fit on LiveCd<br><br>faster access to bigger images <br>from readonly filesystem <br> on harddrive, or <br> network drive, <br><br>readonly<br>
last I heard linux did not reliably write to nfts<br>
we just don't want to risk it even with the<br>
ntfs-ng driver. Some of the users may have<br> extra fragile filesystem on odd vintage os.<br><br>Image on local file system <br>for performance and independence<br><br>Image can be network filesystem<br>if necessary.
<br><br>After they go home they can <br>solve the problems that required<br>them to use the network filesystem<br><br>cryptographic signature verifies validity of image will verify<br>lack of subtle problems case insensitive filenames,
<br>corrupted files, etc. if it's a PKI signature it fits the<br>security model.<br><br clear="all">-- <br>Drew Einhorn
