I'm going through the process of configuring tripwire on one of my
systems and am exploring this issue as well.  I have a stripped
down system so there may be more files that are mutable.  Here's what
I've found so far:

  /etc/amandates     From amanda which is a backup system
  /etc/adjtime       From clock
  /etc/dumpdates     From dump
  /etc/ioctl.save    From init
  /etc/mtab          From mount
  /etc/wtmplock      From login


  /dev/log           Created by sysklogd but can configure to another
                     directory
  /dev/tty[0-9]  Changes ownership
  /dev/ttyS[0-9] Changes ownership 
                 Other terminal devices
  /dev/urandom
  /dev/initctl

I sure there are more files modified in the /dev directory.

I find it unfortunate that /etc cannot be mount read-only.  Will the
FHS address this problem?
