I have been tasked to setup several servers, database, web, mail, file and have been trying to figure out if I should disable prelink or not. prelink is enabled by default in this release (RHEL 6.3).
Does a server running the above services benefit significantly enough with improved performance to justify leaving pre-linking enabled on the system.
I've seen a lot of people discuss the advantages of using pre-linking on a desktop system, but does it make sense to leave it running on a fast server, does anyone have benchmarks on how it improves performance of httpd, smbd, postfix, mysqld.
I would think that most people leave it enabled or don't even know about it.
So part 2 of my question is..
I understand that pre-linking causes changes in a binary file, and therefore aide which is calculating checksums and noting mtimes, it is often tripped because of the pre-linking and not because of a cracker modifying the system binary.
How can I get aide working with prelink. I am aware of this previous post where a user disabled prelink to get aide to work, but that's a workaround and not a fix :-)
Thanks for any tips.
