That's the ticket for prelink.cache. If it changes, there was a change to the system that (can) be important...something in the system libraries (or their directories) changed. > So let's be very explicit.

If you NEVER update the system or install new packages, the _content_ shouldn't change. The atime may change since I think it's scanned by prelink, but I won't swear to that. > On 10/31/07, Rick Stevens <rstevens@xxxxxxxxxxxx> wrote: > > On Wed, 2007-10-31 at 08:51 -1000, Dave Burns wrote: > > > idea?
