prelink speeds up app startup - it does the work once to save startup times repeatedly.
I'm not convinced, for my pattern of usage at least, that the game is worth the candle. On my laptop I start my desktop, a few xterms and maybe Mozilla, then leave them running. Any time that might be saved on startup is outweighed by the inconvenience of having the system become unresponsive when anacron kicks in to perform the prelinking. Which always seems to happen at the most awkward moment. (Yes, I know I can turn it off. And I have.)
Prelink seems to do an enormous amount of work when it runs. Have the developers checked that all of this effort is really necessary?
What might help would be the ability to limit the resources (CPU, disk I/O, whatever) that are used by background processes. Nice is nice, but not powerful enough. Something like cpucap
http://www.rshk.co.uk/projects/cpucap/
would seem to be a better option.

Is there a potential for lots of race conditions if multiple resources (i.e. all of cpu, memory and disk) are throttled?

prelink speeds up app startup - it does the work once to save startup times repeatedly.
Then isn't it more convenient to run it when installing packages using rpm (when I expect some thrashing) and let the user decide if and when to prelink manually installed packages?

Not really, since when you install a new library everything that links to it needs to be prelinked again. Say there's a glibc update; do you really want the computer to thrash for between 10 minutes and half an hour, depending on how fast your hardware is?

hi-
This is mostly a cosmetic issue, but if one opens the FC3T3rc3 "Rlease Notes" window of the installer, the last char of section headings, bullet points, and some bold text is wrapped around to the next line, for example:
"make oldconfig" is displayed as:
"make oldconfi g"

I think that's a known problem. Something to do with a Python/anaconda html library and nested lists methinks. Might be wrong..
Is the releasenotes anywhere to be found?
Just wanna take a look at it :)

It wouldn't be a big problem - if there was an option not to do it, rpm was freed (so you could bacground it/open another console and install another package), and it was stoppable (control+c).

agreed. But as far as i know, the CPU is seldom the limiting factor when running a multi-tasking OS such as Linux. And i am using a 650 Mhz. What i mean, is that i hardly notice when the CPU is chrunching away at full speed, but when something hits disk (updatedb and sometimes memory (OpenOffice dictionary load) hard - it is noticed.
