Program or system function that reverts files?

[johndabomb44]

Hello!

Is there a program or built-in function of CentOS 6 that does something like the following?

1. for ex: /etc/issue states "Welcome!"
2. I change /etc/issue to "Goodbye!" and save changes to file
3. I then reboot system
4. I open /etc/issue and it states "Welcome!"

Basically, is there some kind of revert function or software that stops write changes to files persisting after a reboot?

I have seen this behaviour once, but it wasn't a CentOS system. It was a Raspberry Pi, running Raspbian, and the MicroSD card was dying.

No.

Ok, so if a system is having this behavior then it is because someone programmed the computer in some way to do so?

Probably. Start by looking at /etc/rc.local
