While i haven't tried it yet, it should certainly be possible. The Koha installer merely adds "web resources" (perl, javascript, images, and such), and a couple of configuration files for itself and Apache Koha depends on Apache, MySQL, and Perl language facilities plus Perl modules. The configuration file and the database contain everything unique that Koha "knows" about a particular installation. Indeed, very often i simply do a 'mysqldump' of Koha's database to my own USB stick when i want to work on my library catalog on my laptop elsewhere, instead of on the server itself. Also, i have the same database user setup, so that config files match. Also, a user called 'koha' on the operating system itself, that owns all of Koha's files. Of course, there are security risks with just setting up users on multiple machines this way. i have no experience with zebra, and can't comment on its configuration. A 'lite' version on a stick might assume that these are available on the server you plug it into, BUT have the database (and config) files on the stick itself so you can move between servers. A 'full' version might bundle everything, but the OS. A 'kitchen-sink' version is probably one that you can boot into with a full OS. Now, for some data: A 'du -sh /usr/share/koha' yields 316Mbytes Similar du -sh readings are as follows: 316M    /usr/share/koha 1.4M    /var/lib/mysql/koha3/ 476M    /usr/local/share/perl/ 6.6M    /usr/local/lib/perl/ The first is all the files for Koha's "pages". The second is a relatively freshly-installed Koha database (not much data), and the last two are the Perl modules Koha needs (and some more). This suggests a size under 1 Gig for the whole gig (pun intended) a USB stick throws up interesting possibilities for distribution, since i have now been supplying DVDs for Koha installs in places where no Internet is available. More about that in later mail. regards, krishnan --- On Wed, 14/1/09, James Leech <James.Leech@slq.qld.gov.au> wrote: From: James Leech <James.Leech@slq.qld.gov.au> Subject: [Koha] Running koha from removable media To: koha@lists.katipo.co.nz Date: Wednesday, 14 January, 2009, 2:39 AM Hello   Has anyone ever heard of anyone attempting to run a simple library management system off a USB Stick?   With USB sticks getting larger, and various solutions offering to boot Linux from your portable USB stick, would it be possible to run a version of koha that could manage a small library collection?  I’m not very cluey about client / database solutions, but I noticed one post mentioning Koha running on a standalone PC with the client accessing the localhost.   Also, how large would a koha installation be?   Cheerio,   James   James Leech  Project officer - Keeping Culture Strong State Library of Queensland - Cairns  Reef Terminal Building  Level 1, 1 Spence Street, Cairns  Qld  4870  P.O.
