I want to use a live USB iso of FreeBSD to mount my actual system ans change a config file.

My problem is, I can't mount it because I get an error thay says that the filesystem is "read only" (reffing to the ISO filesystem).

Is there another way to do it? Can I make the filesystem read-write?

Create a mount point under /tmp/, mount the file system there. /tmp is a tmpfs and rw.
