Re: /etc/prelink.cache

I could hear this as either "this file changes too unpredictably, go
ahead and ignore it" or "this file only changes when something
significant happens, it will be a good signal of bad activity,
assuming you keep track of your valid system changes such as yum
updates."

So let's be very explicit. If I never updated my system or installed
new software ever again, would /etc/prelink.cache ever change? Is it a
canary or a cuckoo bird?

Thanks,
Dave

There are a number of files that will change depending on system
activity and that's one of them. Lots of the files in /var/log will
also change (messages, dmesg, boot.log, wtmp, you get the idea).

prelink is run once a day via the system crontab and its control file
/etc/cron.daily/prelink. The cache will change if system libraries are
updated via yum/rpm or you build something that adds libraries to the
normal system directories. This is controlled by /etc/prelink.conf.
