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
/dev/tty[0-9] Changes ownership
/dev/ttyS[0-9] Changes ownership
Other terminal devices
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?
