Good morning,
thank you very much for the excellent Fedora.
I worry about safety, surf the Internet without antivitus.
Is it possible to configure the system or boot partition for the linux
read-only?
Thus, placing the system in a partition of the data reading and a read /
write the system is not corrupt.

Greetings and thank you very much.
