Subject: introduced prerun scripts.
X-Git-Tag: submit/tizen/20150602.060836~14
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ff58b3c839a627da9d2e894df78fd8b699123e20;p=platform%2Fadaptation%2Femulator%2Fsystem-plugin-emulator.git

introduced prerun scripts.

This script is executed from initramfs.
It is very useful for manipulating some files on rootfs before init.
(Configuration files, ...)
