Translations:OpenRC/Baselayout 1 to 2 migration/8/en
From Gentoo Wiki
Originally Gentoo's rc system was built into baselayout 1 and written entirely in bash. This led to several limitations. For example, certain system calls need to be accessed during boot and this required C-based callouts to be added. These callouts were each statically linked, causing the rc system to bloat over time.
