Not true. There are a few others before 'init', including
'plugins_loaded' (this is handy as it's the very earliest hook
available to plugins) and 'setup_theme' among a few others.

However, the 'init' hook is the earliest hook at which the entire
WordPress environment and all its functions are available. So if your
plugin is trying to catch something at its earliest point then, yes,
'init' is usually the one to go for, but not always.

Haluk, http://codex.wordpress.org/Query_Overview is also worth a read
if you're interested in how and when WordPress does what it does.
