Developing a kiosk type system - advice needed
I am developing a
"kiosk" type of system, where I want to a) boot up fast and b) be able to switch
off and back on and restart with a clean image.
1Gb filesys to play with (CF or similar) and 128-256mb
I was hoping to do
something like this:
1. Make the disk
2. Use software suspend with KEEPIMAGE to always start from a
stored image, and do the following in a resume script:
a. Load the 'writeable' parts of the system (e.g. /tmp,
/var) from disk images and mount them into the right mount
b. Start up X and appropriate
I don't want any
data (e.g. cookies, cache, logs etc) to be saved, so that the box can be
restored just by switching it off and back on.
I was looking at
using loop devices to mount /var and /tmp, but how can I make sure that the
image on the disk won't be changed? Can I mount a loop device so the ramdisk is
writeable but the disk file isn't? Or can anyone suggest a better way of doing
Thanks for your
