 ### notes
 
-* **gentoo ebuild**: openrc's start-stop-daemon lacks support for easy creation of unprivileged daemons in chrooted environments with logging enabled, which sear.c absolutely requires due to it being in early alpha unstable stage. [a pull request was submitted to openrc that adds such features](//http://github.com/OpenRC/openrc/pull/517); until it's merged and until it's changes are gentoo, sear.c's init script is unusable.
