I have a small linux box with a dedicated task of reading sensor data and comparing values against a read only (ie i won't write stuff to it, but haven't done anything to make it actually readonly) local database.
The system doesn't need to write anything onto the file system,except maybe some temp files created when the local web service is accessed (web page shows the data, but doesn't log it)
The system autoboots when power is applied, and it is turned off by just cutting power.
Is there a good guide for setting up a system to be cool with abrupt power offs? I am currently using ubuntu (cause i am familiar with it and it runs well on the fit pc 2 that i am using)
Or given that I have no applications writing anything to disk (web server temp files are the exception), can I get away with not modifying the system? The only important point is there is no human to intervene if the boot process throws a question out the terminal and hangs waiting for a response.
