Oh, and there's a good discussion on security levels and what they do
in init(1). For example:
1 Secure mode - immutable and append-only flags may not be changed;
disks for mounted filesystems, /dev/mem, and /dev/kmem are read-
only.
so that's another reason to use chflags on sensitive files.
You might even want to go as far as setting immutable on all
distribution media files, like /usr/bin/*.
Be careful out there!
