"Thus, Linux's changes may not be as big from version
to version, but they tend to be more thoroughly tested and stable.
What most users will like in this distribution starts with a faster
boot-up for Linux.
"1. Fast boot. Older versions of Linux spend a lot of time
scanning for hard drives and other storage devices and then
partitions on each of them. This eats up a lot of milliseconds
because it looks for them one at a time. With the 2.6.30 boot-up,
however, instead of waiting for this to get done the rest of the
kernel continues to boot-up. At the same time, the storage devices
are being checked in parallel, two or more at a time, to further
improve the system's boot speed."
