So flip the write-protect switch on the floppy.  No program is a
panacea.  This sounds like a wonderful tool, regardless.

Without knowing the full mechanism by which tripwire works, discussions
like this are of limited usefulness.  If your system regularly has been
compromised to the point that you can't trust your kernel, you
shouldn't be trusting Tripwire alone anyway.  If we're going to be
paranoid, make a miniroot disk, and put all the stuff on there.  I
kinda doubt it would all fit, however.  A floppy with tripwire, related
programs, a known good copy of the runtime C library, and the database
should be enough.
