Subject: phase2: rely on rsync to merge updated SDK components
X-Git-Tag: v1~179
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2615ef07ba8545f3dbec4d31b40e801e8fe1f541;p=buildbot.git

phase2: rely on rsync to merge updated SDK components

Relying on the file modtime is unreliable so we cannot trust tar's
--keep-newer-files to properly overwrite changed SDK components.

Extract into a different directory instead and use rsync with checksum
mode to replace updated SDK files.
