I have a picture frame (old laptop) which I have a HD install on, is it possible to make the root partition '/' read only?

I want to do this so I can switch it off without shutting it down.

Any ideas?

Is it possible to make the HD switch off all together once booted ? (all pictures are sucked over the network..)

Cheers,

In /etc/fstab I believe you can add the flag ,ro (read only) to all the automatic mount points...however I dont know if that the file isnt overwritten by the KNOPPIX starup script stuff at boot time

Give it a shot and see if that works for you

Thanks,

I should have given more info on what I have and havn't tried.

I tried to mount / as ro in fstab, but it failed to boot (had to use cd to boot again and fix..

I have also tried to use 'mount -remount-oro/mnt/.....' but I get 'DeviceBusy' or similar.
