It may try sda first, but I don't think that is something new. OK a list of files found in /dev then, why would anybody try to mount sda if sda1 is present? I can see trying to mount sda if there was no partition table present, but if there is a table why try? It's going to fail. Doesn't matter, there are acceptable replacements for that functionality, just another package that's not part of Fedora that won't need to be maintained going forward.

It would be relatively easy to give the teacher's laptop a special menu line in the XO icon or in the console so that no command line interface would be needed. Essentially I am doing this sort of change with a script which works after the XO install (it could, of course, also be baked into the build). In the latter case, all of the laptops would have the extra menu line so the school server could be configured only to accept the teacher's click (e.g. identify teacher by serial-number so that only the teacher's public key would match).

Re: [Server-devel] usbmount alternatives
Hi Daniel, Can you tell me what plans there are for the XS beyond version 0.7 and who would be undertaking them. Thanks, Tim -- From: Daniel Drake d...@laptop.org Sent: Tuesday, November 13, 2012 9:05 AM This should be discussed on server-devel. I'd be happy to advise on any usbmount issues reported there.
