I’m no longer at Logic Supply, but if people still have questions I can do my best to get them answered. I’ve created a new thread for this purpose on the RapidRollout forums:

Configuring Ubuntu for read-only storage

I have done this "Read-Only Linux System" procedure on a more "normal" computer (Intel Atom, Debian squeeze), and it works fine. But it fails on the Dockstar. It boots, it just isn't read-only. I get the following in dmesg: [ 12.960395] aufs: module is from the staging directory, the quality is unknown, you have been warned. [ 12.993986] aufs 2-standalone.tree-32-20100125 [ 13.003956] aufs test_add:218:mount[124]: unsupported filesystem, /root.ro (rootfs) I end up with no /rw or /ro mount points. Ideas?
