Re: permissions

Note two things about mounting system read-only:

1) on many systems, including Suns, you can "remount" a file system
r/w if you are root

2) mounting something read-only still allows writing via the raw
device if permissions are set incorrectly, or if running as root.


Thus, mounting a partition ro is no guarantee things can't be changed.
This is why we recommend that the Tripwire executable and database go
on removable media that has a *physical* write-protect lock that
cannot be undone in software.
