Based on http://meta.emacs.stackexchange.com/questions/65/would-we-prefer-dotemacs-emacs-init-el-or-init-fileWould we prefer [dotemacs], [.emacs], [init.el] or [init-file]? , init should be init-file when referring to anything related to startup configuration (including debugging).
The second question (regarding events at startup) probably still falls under init-file since how do I change it
is handled under the init-file
(however what is being triggered
has to do with how Emacs handles initialization).
Perhaps to ensure clarity a startup should be used/created to deal with how Emacs starts up (the entire process, not just the init-file)
