Greetings,
There is a Linux distro called "Voyage Linux" that runs read-only.
There are scripts that can be run as root called 'remountrw' and remoutro'
to change modes as neccessary.
Sadly, Voyage Linux is written to run on the x86 andis not available
for the ARM processor. But if someone ever converts it to ARM I will
switch in a heartbeat! I have several Voyage boxes being used for data
collection and love them! It would certainly be sweet to have Voyage on
the BBB :)
See: http://linux.voyage.hk
Enjoy!

Hello,
I'd need the SD image I prepared for the xM to be supplied to people
without them changing a single bit in it. Also, this avoids write failure
with power supply failures and increases the life of the SD.
From my understanding this can be done by mounting the rootfs as read-only
at some point in the boot and writing any change to the RAM without making
them persistent. But I'm not expert in the bootstrap process with Linux.
The only similar case I know in detail so far is with Ubuntu 10.10
https://ccrma.stanford.edu/~eberdahl/satellite/ and it has two uInitrd
images for boot, one with aufs enable and the other without. They only
differ in a couple of scripts and if one wants changes to be persistents it
is enough to mv files in the boot partition in order for the bootloader to
pick the right one.
Now, I'm using debian and the rcn-ee builds. Here the boot partition is
different it uses initrd.img and zImage. I'm not sure what to do here since
it is a different boot method.
Are there any suggestions on how to reach my goal? Any simple solution,
even performed with an init script after bootstrap would be fine as a
starter.
Regards
