HD Install :: start apps at boot?
@lucky13: Ah. I first thought that link referred to cloop-readahead, but it was the "actual" one. Well, I took a look at that, and it is done the "ubuntu"-way - it starts early with a list of all files accessed during boot, reading them all in sequence - which isn't too good for low-ram machines, if the file is read too early or too late. Slow cd drives may also not benefit from this continuous read, slowing other cd-accesses.
When used in an appropriate spot, and timed right, it results in a speedup.
