I just installed Debian, now how do I make the whole system readonly? (embedded sys)
Hi
I just installed Debian (Lenny) onto a Compact Flash card. This is to be used in an embedded system that only does one thing (runs a custom program). It does not need to be able to write to the disk at all, so I'm hoping to mount the file system readonly or similar. This makes sure that when people turn it off without shutting down properly, it does not cause any problems as the system will still boot up next time as though it had been untouched.
Can anyone explain how or lead me in the right direction as to how to make my current Debian install readonly? Is it simply about setting the appropriate options in fstab?
@linus72, its a complete linux install, not a live cd because i need to add my own packages.
Thanks for the help catkin! The link is going to be very useful for me. What about the swap partition though, is there a way to disable it as well or just a tmpfs for the swap?
